Camera Adaptor and Digital Microscope-6

6 Reduction Lens and its dimension

            Most of the ocular tubes are 23.2 mm. The adaptor should insert into this tube in one end while the other end should be screwed into the C-mount camera. This constitute the interface standard of the Reduction Lens as shown below

Basic dimensions of the
AMA(Adjustable Microscope Adaptor),      FMA (Fixed Microscope Adaptor),
ATA(Adjustable Telescope Adaptor),          FTA(Fixed Telescope Adaptor)       

For the stereo microscope with 30mm or 30.5 mm ocular tubes, the 23.2mm to 30 mm adaptor or 23.2mm to 30.5 mm adaptor for the eyepiece adaptor should be chosen. They are shown as follows

23.2mm to 30 mm adaptor and 23.2mm to 30.5 mm adaptor for the eyepiece adaptor

The final configuration of the Camera+Adaptor should look like this:

Camera+AMA,Camera+FMA,Camera+ATA and Camera+FTA

7 Conclusion

            If you configure your optical microscope to digital microscope, you can try any ways to do it. But I think the best way is to directly purchase a C-mount camera and an adaptor. Then screw the adaptor to the C-mount camera, finally insert the 23.2mm end to the trinocular tube or eyepiece tube.
