This image of Convallaria majalis rhizome with concentric vascular bundles was acquired using the CS895CU Color Camera.

These cameras are available with either monochrome or color sensors. Each camera includes a USB 3.0 interface for compatibility with most computers. Included with each camera is our ThorCam software for use with Windows 7, 8.1, and 10 operating systems. We offer support for LabVIEW, MATLAB, and .NET. Developers can leverage our fully featured API and SDK.

The camera aperture has SM1 (1.035"-40) threading for compatibility with Ø1" Lens Tubes; an adjustable C-Mount (1.000"-32) adapter is factory installed for out-of-the-box compatibility with many microscopes, machine vision camera lenses, and C-Mount extension tubes. Each monochrome camera features a clear window, while each color camera features an IR blocking filter. This optic can be removed and replaced with another Ø25 mm or Ø1" optic up to 1.27 mm thick when using the camera's C-mount adapter. Without this adapter, the maximum filter thickness is 4.4 mm.

Four, 4-40 tapped holes provide compatibility with our 30 mm cage system. Two 1/4"-20 tapped holes on opposite sides of the housing are compatible with imperial Ø1/2" Posts. The combination of flexible mounting options and compact size makes these cameras the ideal choice for integrating into home-built imaging systems as well as those based on commercial microscopes.

Thorcam GUI Window

Camera Control and Image Acquisition

Camera Control and Image Acquisition functions are carried out through the icons along the top of the window, highlighted in orange in the image above. Camera parameters may be set in the popup window that appears upon clicking on the Tools icon. The Snapshot button allows a single image to be acquired using the current camera settings.

The Start and Stop capture buttons begin image capture according to the camera settings, including triggered imaging.

Timed Series and Review of Image Series

The Timed Series control, shown in Figure 1, allows time-lapse images to be recorded. Simply set the total number of images and the time delay in between captures. The output will be saved in a multi-page TIFF file in order to preserve the high-precision, unaltered image data. Controls within ThorCam allow the user to play the sequence of images or step through them frame by frame.

Measurement and Annotation

As shown in the yellow highlighted regions in the image above, ThorCam has a number of built-in annotation and measurement functions to help analyze images after they have been acquired. Lines, rectangles, circles, and freehand shapes can be drawn on the image. Text can be entered to annotate marked locations. A measurement mode allows the user to determine the distance between points of interest.

The features in the red, green, and blue highlighted regions of the image above can be used to display information about both live and captured images.

ThorCam also features a tally counter that allows the user to mark points of interest in the image and tally the number of points marked (see Figure 2). A crosshair target that is locked to the center of the image can be enabled to provide a point of reference.

Third-Party Applications and Support

ThorCam is bundled with support for third-party software packages such as LabVIEW, MATLAB, and .NET. Both 32- and 64-bit versions of LabVIEW and MATLAB are supported. A full-featured and well-documented API, included with our cameras, makes it convenient to develop fully customized applications in an efficient manner, while also providing the ability to migrate through our product line without having to rewrite an application.

Performance Considerations

Please note that system performance limitations can lead to "dropped frames" when image sequences are saved to the disk. The ability of the host system to keep up with the camera's output data stream is dependent on multiple aspects of the host system. Note that the use of a USB hub may impact performance. A dedicated connection to the PC is preferred. USB 2.0 connections are not supported.

First, it is important to distinguish between the frame rate of the camera and the ability of the host computer to keep up with the task of displaying images or streaming to the disk without dropping frames. The frame rate of the camera is a function of exposure and readout (e.g. clock, ROI) parameters. Based on the acquisition parameters chosen by the user, the camera timing emulates a digital counter that will generate a certain number of frames per second. When displaying images, this data is handled by the graphics system of the computer; when saving images and movies, this data is streamed to disk. If the hard drive is not fast enough, this will result in dropped frames.

One solution to this problem is to ensure that a solid state drive (SSD) is used. This usually resolves the issue if the other specifications of the PC are sufficient. Note that the write speed of the SSD must be sufficient to handle the data throughput.

Larger format images at higher frame rates sometimes require additional speed. In these cases users can consider implementing a RAID0 configuration using multiple SSDs or setting up a RAM drive. While the latter option limits the storage space to the RAM on the PC, this is the fastest option available. ImDisk is one example of a free RAM disk software package. It is important to note that RAM drives use volatile memory. Hence it is critical to ensure that the data is moved from the RAM drive to a physical hard drive before restarting or shutting down the computer to avoid data loss.

Triggered Camera Operation

Our scientific cameras have three externally triggered operating modes: streaming overlapped exposure, asynchronous triggered acquisition, and bulb exposure driven by an externally generated trigger pulse. The trigger modes operate independently of the readout (e.g., binning) settings as well as gain and offset. Figures 1 through 3 show the timing diagrams for these trigger modes, assuming an active low external TTL trigger.

Camera Timing Diagram
Click to Enlarge
Figure 1: Streaming overlapped exposure mode. When the external trigger goes low, the exposure begins, and continues for the software-selected exposure time, followed by the readout. This sequence then repeats at the set time interval. Subsequent external triggers are ignored until the camera operation is halted. For the definition of the TTL signals, please see the Pin Diagrams tab.
Timing Diagram
Click to Enlarge
Figure 2: Asynchronous triggered acquisition mode. When the external trigger signal goes low, an exposure begins for the preset time, and then the exposure is read out of the camera. During the readout time, the external trigger is ignored. Once a single readout is complete, the camera will begin the next exposure only when the external trigger signal goes low.
Camera Timing
Click to Enlarge
Figure 3: Bulb exposure mode. The exposure begins when the external trigger signal goes low and ends when the external trigger signal goes high. Trigger signals during camera readout are ignored.

Camera Specific Timing Considerations

Due to the general operation of our CMOS sensor cameras, as well as typical system propagation delays, the timing relationships shown above are subject to the following considerations:

  1. The delay from the external trigger to the start of the exposure and strobe signals is typically 270 ns for all triggered modes (standard and PDX/Bulb).
  2. For PDX/Bulb mode triggered exposures, in addition to the 270 ns delay at the start of the exposure, there is also a 13.72 µs integration period AFTER the falling edge of the external trigger. This is inherent in the sensor operation. It is important to note that the Strobe_out signal includes the additional 13.72 µs integration time and therefore is a better representation of the actual exposure time. Our suggestion is to use the Strobe_out signal to measure your exposure time and adjust your PDX mode trigger pulse accordingly.

External Triggering

Camera Triggering in ThorCam Software
Click to Enlarge

Figure 4:
The ThorCam Camera Settings window. The red and blue highlighted regions indicate the trigger settings as described in the text.

External triggering enables these cameras to be easily integrated into systems that require the camera to be synchronized to external events. The Strobe Output goes high to indicate exposure; the strobe signal may be used in designing a system to synchronize external devices to the camera exposure. External triggering requires a connection to the auxiliary port of the camera. We offer the 8050-CAB1 auxiliary cable as an optional accessory. Two options are provided to "break out" individual signals. The TSI-IOBOB provides SMA connectors for each individual signal. Alternately, the TSI-IOBOB2 also provides the SMA connectors with the added functionality of a shield for Arduino boards that allows control of other peripheral equipment. More details on these three optional accessories are provided below.

Trigger settings are adjusted using the ThorCam software. Figure 4 shows the Camera Settings window, with the trigger settings highlighted with red and blue squares. Settings can be adjusted as follows:

  • "Hardware Trigger" (Red Highlight) Set to "None": The camera will simply acquire the number of frames in the "Frames per Trigger" box when the capture button is pressed in ThorCam.
  • "Hardware Trigger" Set to "Standard": There are Two Possible Scenarios:
    • "Frames per Trigger" (Blue Highlight) Set to Zero or >1: The camera will operate in streaming overlapped exposure mode (Figure 1).
    • "Frames per Trigger" Set to 1: Then the camera will operate in asynchronous triggered acquisition mode (Figure 2).
  • "Hardware Trigger" Set to "Bulb (PDX) Mode": The camera will operate in bulb exposure mode, also known as Pulse Driven Exposure (PDX) mode (Figure 3).

In addition, the polarity of the trigger can be set to "On High" (exposure begins on the rising edge) or "On Low" (exposure begins on the falling edge) in the "Hardware Trigger Polarity" box (highlighted in red in Figure 4).

 

Example Camera Triggering Configuration using Scientific Camera Accessories

Figure 5: A schematic showing a system using the TSI-IOBOB2 to facilitate system integration and control.
While the diagram shows the back panel of our Quantalux™ sCMOS Camera, our Scientific CCD cameras can be used as well.

As an example of how camera triggering can be integrated into system control is shown in Figure 5. In the schematic, the camera is connected to the TSI-IOBOB2 break-out board / shield for Arduino using a 8050-CAB1 cable. The pins on the shield can be used to deliver signals to simultaneously control other peripheral devices, such as light sources, shutters, or motion control devices. Once the control program is written to the Arduino board, the USB connection to the host PC can be removed, allowing for a stand-alone system control platform; alternately, the USB connection can be left in place to allow for two-way communication between the Arduino and the PC. Configuring the external trigger mode is done using ThorCam as described above.

What is the dark current noise of this camera at 25°C please?
YLohia  (posted 2018-11-07 03:10:31.0)
Hello, thank you for contacting Thorlabs. Could you please clarify what you mean by "dark current noise"? I'm not sure if you are using it as an informal name for dark current shot noise. If that's the case, this quantity for non-defective pixels is very small. Or are you referring to the "dark current," which is expressed as a mean value in electrons/pixel/second? Please note that the mean dark current is internally compensated, and measurement would be difficult and would not provide much insight into the performance of the camera. If you're referring to the read noise, it is specified to be <2.5e- RMS. If you have further questions, please contact us at techsupport@thorlabs.com since you did not leave you email.

Scientific Camera Optional Accessories

TSI-IOBOB2 Diagram
Click for Details

A schematic showing a TSI-IOBOB2 connected to an Arduino to trigger a compact scientific camera.

These optional accessories allow for easy use of the auxiliary port of our compact scientific (sCMOS & CMOS) or scientific CCD cameras. These items should be considered when it is necessary to externally trigger the camera, to monitor camera performance with an oscilloscope, or for simultaneous control of the camera with other instruments.

For our USB 3.0 cameras, we also offer a PCIe USB 3.0 card and extra cables for facilitating the connection to the computer.

Auxiliary I/O Cable (8050-CAB1)
The 8050-CAB1 is a 10' (3 m) long cable that mates with the auxiliary connector on our scientific cameras* and provides the ability to externally trigger the camera as well as monitor status output signals. One end of the cable features a male 12-pin connector for connecting to the camera, while the other end has a male 6-pin Mini Din connector for connecting to external devices. This cable is ideal for use with our interconnect break-out boards described below. For information on the pin layout, please see the Pin Diagrams tab above.

*The 8050-CAB1 cable is not compatible with our former-generation 1500M series cameras.

Interconnect Break-Out Board (TSI-IOBOB)
The TSI-IOBOB is designed to "break out" the 6-pin Mini Din connector found on our scientific camera auxiliary cables into five SMA connectors. The SMA connectors can then be connected using SMA cables to other devices to provide a trigger input to the camera or to monitor camera performance. The pin configurations are listed on the Pin Diagrams tab above.

Interconnect Break-Out Board / Shield for Arduino (TSI-IOBOB2)
The TSI-IOBOB2 offers the same breakout functionality of the camera signals as the TSI-IOBOB. Additionally, it functions as a shield for Arduino, by placing the TSI-IOBOB2 shield on a Arduino board supporting the Arduino Uno Rev. 3 form factor. While the camera inputs and outputs are 5 V TTL, the TSI-IOBOB2 features bi-directional logic level converters to enable compatibility with Arduino boards operating on either 5 V or 3.3 V logic. Sample programs for controlling the scientific camera are available for download from our software page, and are also described in the manual (found by clicking on the red Docs icon below). For more information on Arduino, or for information on purchasing an Arduino board, please see www.arduino.cc.

The image to the right shows a schematic of a configuration with the TSI-IOBOB2 with an Arduino board integrated into a camera imaging system. The camera is connected to the break-out board using a 8050-CAB1 cable that must be purchased separately. The pins on the shield can be used to deliver signals to simultaneously control other peripheral devices, such as light sources, shutters, or motion control devices. Once the control program is written to the Arduino board, the USB connection to the host PC can be removed, allowing for a stand-alone system control platform; alternately, the USB connection can be left in place to allow for two-way communication between the Arduino and the PC. The compact size of 2.70" x 2.10" (68.6 mm x 53.3 mm) also aids in keeping systems based on the TSI-IOBOB2 compact.

USB 3.0 Camera Accessories (USB3-MBA-118 and USB3-PCIE)
We also offer a USB 3.0 A to Micro B cable for connecting our cameras to a PC (please note that one cable is included with each USB 3.0 camera). The cable measures 118" long and features screws on either side of the Micro B connector that mate with tapped holes on the camera for securing the USB cable to the camera housing. When operating USB 3.0 cameras it is strongly recommended that the Thorlabs-supplied USB 3.0 cable be used, with the retention screws securely fastened. Due to the high data rates involved, users may experience problems when using generic USB 3.0 cables.

Cameras with USB 3.0 connectivity may be connected directly to the USB 3.0 port on a laptop or desktop computer. USB 3.0 cameras are not compatible with USB 2.0 ports. Host-side USB 3.0 ports are often blue in color, although they may also be black in color, and typically marked "SS" for SuperSpeed. A USB 3.0 PCIe card is sold separately for computers without an integrated Intel USB 3.0 controller. Note that the use of a USB hub may impact performance. A dedicated connection to the PC is preferred.
