Sensors and Functionality
These ultra compact, lightweight CCD cameras feature USB connections, making them extremely versatile for a wide range of applications including industrial automation, quality control, medical imaging, microscopy, and security technology. The DCU223 models are equipped with a high-quality SONY 1/3" CCD sensor with XGA resolution (1024 x 768) and provide a full frame repetition rate of 30 fps. The DCU224 models have a 1/2" CCD sensor with SXGA resolution (1280 x 1024) and provide a full frame repetition rate of 15 fps.
SM1 Thread Compatibility
Compatibility of the CCD Camera with Thorlabs' SM1 Internal or External Threadings via the Included SM1 (1.035"-40) Adapters
For all models, higher frame rates can be achieved by using the Area of Interest (AOI) or Binning functions; the former increases the frame rate by only reading a selected area of the sensor, whereas the latter increases the frame rate by combining pixel readings before transferring them to the PC, but in this case, image resolution is sacrificed. The computer can communicate digitally with the camera through the USB 2.0 interface, thus enabling the user to transmit images and control camera settings seamlessly.
Each CCD camera comes with ThorCam, our Windows-compatible software package on CD. In addition, the cameras are supported by an extensive software development kit. Standard drivers like Direct Show (WDM), Active X, and TWAIN are provided. In addition, over 20 demo programs (including source code) are supplied. A USB cable for connecting the camera to a PC is also included. These cameras can be used with the latest release of µManager to obtain monochrome images (this includes the color USB CCD cameras).
The DCU223 CCD cameras are fully compatible with our standard C-Mount Camera Lenses and High-Magnification Zoom Lenses, which are sold separately. Our standard lenses include fixed focal lengths of 3.5 mm - 75 mm with maximum apertures of up to f/0.95, as well as an 18 - 108 mm f/2.5 zoom lens. Our high-magnification zoom lenses are a modular system that features magnification from 0.07 - 28.
Included Mounting Adapters
The C-Mount threading of the CCD camera can be easily connected to components with Thorlabs' standard SM1 (1.035"-40) thread via one of the two included SM1 adapters, as shown in the photo to the right. Additional adapters may be purchased below. A mounting adapter plate is also provided with the CCD camera; by using the included M4 x 10 mm or 8-32 x 3/4" cap screw, the camera can be threaded onto Thorlabs' TR series Ø1/2" posts. Every unit also ships with four M3 x 6 mm screws for mounting the adapter plate to the camera.
The optional CAB-DCU-T1 and CAB-DCU-T2 cables can replace the standard USB connection while also enabling the use of the additional trigger input and output ports of these cameras. The exposure and readout/transfer events of the camera can be initiated via the input trigger; external events like strobe lights can be triggered by the camera through the output trigger . The trigger configuration, i.e. the source of the input trigger and the timing for the output trigger, can be set through the provided software or the LabVIEW drivers.

Pixel Sensitivity of the CCD Camera
Pixel sensitivity versus wavelength plots are shown at the right for the monochromatic and color versions of these CCD cameras. The color model incorporates a removable IR filter that blocks the spectral region marked by the pink background. For this model, the popular Bayer color filter array is used to acquire digital color images. The filter is based on the repeating 2 x 2 pattern shown to the left; half of the total number of pixels are green (G), and the remaining pixels are equally divided between red (R) and blue (B).
Due to this arrangement, each pixel is only sensitive to one color, and as a result, the overall sensitivity of the color image is three times lower than that achievable with a monochromatic sensor. Thus, B&W CCD cameras are preferred in low-light situations. Even though only one third of the color information is obtained at each pixel, a full-color image can be achieved through the use of various demosaicing algorithms that interpolate a set of red, green, and blue B G B G values at each point.
