CMOS Cameras: USB 2.0 and USB 3.0
USB 2.0 with Trigger Input
GUI and Software Package Included
High-Sensitivity USB 3.0 with Trigger Input
SM1 Thread Compatibility
These compact, lightweight CMOS cameras are available with either a monochrome (M models) or color (C models) sensor. They can be used in a wide range of applications from microscopy to monitoring. Our CMOS cameras offer a full-frame resolution of 1280 x 1024 pixels. All camera series are controlled and powered via a standard 5 V USB 2.0 or 3.0 port.
The DCC1240 and DCC3240 high-sensitivity CMOS cameras include CMOS sensors that allow for switching between rolling and global shutter mode, offer a considerably higher dynamic range, and include an input for an external trigger. A brief comparison of the features available in each model is presented in the table below. For a detailed list of specifications, see the Specs tab.
For quantitative applications requiring low noise, high quantum efficiency cameras, consider our Quantalux® sCMOS and Kiralux® CMOS Cameras.
USB and Trigger Cables
Graphs of the camera response as a function of wavelength are presented here as a comparison between the different camera lines available on this page. Individual sensitivity curves are provided in the tables below.

ThorCam Graphical User Interface (GUI)
ThorCam is a powerful image acquisition software package that is designed for use with our cameras on 32- and 64-bit Windows® 7 or 10 systems. This intuitive, easy-to-use graphical interface provides camera control as well as the ability to acquire and play back images. Single image capture and image sequences are supported. Application programming interfaces (APIs) and a software development kit (SDK) are included for the development of custom applications by OEMs and developers. The SDK provides easy integration with a wide variety of programming languages, such as C, C++, C#, and Visual Basic .NET. Support for third-party software packages, such as LabVIEW, MATLAB, and µManager* is available.
*µManager control of Zelux and 1.3 MP Kiralux cameras is not currently supported. When controlling the Kiralux Polarization-Sensitive Camera using µManager, only intensity images can be taken; the ThorCam software is required to produce images with polarization information.

Back of Camera with Input for External Trigger
The DCC1240M monochrome and DCC1240C color high-sensitivity USB 2.0 CMOS cameras include CMOS sensors that allow for switching between rolling and global shutter mode, offer a high dynamic range and include an input for an external trigger. The cameras are controlled and powered via a USB 2.0 connection. These cameras can achieve frame rates up to 98 fps (reduced ROI).
Each camera is shipped with C-mount to internal SM1 and C-mount to external SM1 adapters (also sold separately below). Taps in the bottom of the camera allow for post mounting with 8-32 or M4 screws.
Our color CMOS cameras have an IR shortpass filter that cuts off transmission above 650 nm. Removing the filter will expose the CMOS sensor to the environment, which could result in dust entering the camera and causing the performance to deteriorate. For those who are very familiar with cameras and sensors, it is possible to change the filter yourself in a cleanroom environment. If you are not comfortable performing this procedure, please send the camera to Thorlabs where our skilled technicians have the tools to safely remove the filter without damaging the camera. Contact technical support for assistance.
These cameras are fully compatible with our C-Mount Camera Lenses and High-Magnification Zoom Lenses that are sold separately. Our standard lenses include fixed focal lengths from 3.5 mm to 75 mm with maximum apertures of up to f/0.95, as well as an 18 - 108 mm focal length, f/2.5 zoom lens. Our high-magnification zoom lenses are a modular system that features magnifications from 0.07 to 28.
The DCC3240M monochrome camera has a USB 3.0 connection for improved performance. Compared to the DCC1240, the DCC3240M camera is capable of a faster frame rate (60.0 fps vs. 25.8 fps in Free Run Mode) and lower trigger delay (as low as 3 µs vs. 20 µs). The camera is powered via the USB port and also has two GPIOs (General Purpose I/O) that allow it to serve as a trigger for peripheral devices. Faster than the DCC1240 cameras, it can achieve a maximum frame rate of 229 fps (limited ROI).
The front aperture features an internal C-mount thread. The bottom of the housing has a 6 mm deep 1/4"-20 tap, so adapters are included for easy post mounting using either the 8-32 or M4 standard. These camera can also be connected to SM1-Threaded Lens Tubes using the adapters sold at the bottom of this page.
