GXM 0.75X Camera Coupler for MZ Series MonoZoom Microscopes for use with C-Mount Microscope Cameras.
Camera couplers attach to the top of a monozoom zoom body and a c-mount microscope camera can be screwed onto them.
The magnification of the coupler will affect the field of view that the camera will see of your subject and can be used to control the overall magnification of the monozoom system without affecting the working distance.
It should be noted that as coupler magnifications decrease , depending on the size of the sensor, there is an increased chance of vignetting (black circle appearing around the image). It should also be noted that, as with all microscope systems, a higher resolution image will be obtained by increasing the magnification of the objective rather than by increasing the magnification of the coupler, but a higher power objective will reduce the working distance of the microscope.
Please also note that for each 2x increase in magnification you will need at least 4X more light in order to present the same amount of light to the camera - don't save your money on lighting - it usually isn't worth it!.
