DCM (USB 2.0)
Digital Video Cameras for Microscopes


The DCM video cameras are digital video cameras specially designed for microscopes. They work perfectly with all kinds of optical microscopes, such as biological microscopes, metallurgical microscopes and stereomicroscopes. The images of the observed specimen or samples can be genuinely displayed on the computer screen. The powerful software ScopePhoto included with the camera ensures simple and convenient operation on the images captured from a microscope.

1) The DCM USB microscope video cameras employ newly designed optical system of fully coated, based on MTF (modulation Transfer Function) analysis, for improved image flatness and contrast. The images are brighter and distinct even at the periphery of the view field. They offer excellent performance combined with plan-achromatic objectives system microscopes. They are specially designed for microscopes with the special optical specifications of microscopes in mind, such as eyepiece view field of WF10x-18mm and the parfocalization of objectives.
2) They provide a wide view field, which closely matches the microscope's view field of 18mm.
3) These video cameras can be inserted directly into the ocular-tube of video port of the microscope, no matter monocular head, binocular head or trinocular head. With the included adaptors of φ30mm or φ30.5mm, it can also be used on a stereomicroscope.
4)Strong metal body.
5) True color

Introduction about software ScopePhoto

ScopePhoto is an image processing software professionally designed for digital cameras, including DCM130, DCM200, DCM300, and DCM500. In addition to basic image file operations and processing, ScopePhoto has the following characteristic specially designed for scientific analysis. The main functions of ScopePhoto are listed below:

a) Image archival with data attachment (*.PTL format, other formats are also supported)
b) Image capture through VFW and Twain interface
c) Image cut-&-paste from image to image, image to file
d) Image basic operations like other similar software are included in the image menu. At here you can adjust the image at ease
e) Image layer operation specially designed for the measurement operation (Layer technique is used to separate the measured results and the different results can be put on different layers)
f) Image processing filter for noise reduction and enhancement (image enhancement filters. edge enhancement filters, morphology operation filters. user defined kernel filter, include convolution and morphological filters)
g) Image arithmetic operation between image and image, image and digital number (including AND, OR, XOR, NAND, NOR, NOT, Add, Subtract, Multiply, Divide, Absolute, Min, Max, Average, Invert, Logarithm, Exponential, Square Root, Square, X to the power of Y operation)
h) Image pseudocode, range, segmentation operations are also include in the application
i) Image zooming and panning operations
