Microscope cameras often have a smaller field of view than the image seen through an eyepiece, thanks to their small sensor. By using the ToupTek 0.37 x reducer lens, the available field of view can be significantly increased, although the resolution of the image is reduced.
The reducer lens has a C-mount thread, making it easy to mount on ToupCam UHP and ToupCam CM cameras. It can also be mounted in front of ToupCam cameras that fit into the 23.2 mm shutter, but requires the appropriate C-mount adapter.
The Touptek 0.37x reducer lens can be mounted in a 23.2 mm eyepiece mount; if the eyepiece mount of your microscope is 30 or 30.5 mm in diameter, the appropriate adapter ring is required.
The reducer is compatible with sensors with 1/4"-1/3" image diameters.
