HAYEAR 0.5X Reduction Lens Eyepiece Lens 23.2mm Mounting with 30mm 30.5mm Ring Adapter Applicable for Biomicroscope Stereo Microscope

Plugged into a Windows laptop, using the Windows camera app, no issues.For my monocular compound microscope, fits perfectly into the mono tube, and I use the 0.5X extender for good pictures and video.For the Stereo zoom microscope, using a focusing adapter (1/2.3) that came with the microscope and just screwed the camera (without 0.5X extender) into the C-mount in the trinocular port. No issues, same good pictures and videos.Reasonable price for a nice camera; as a hobbyist, I couldn't ask for more.When it's time to publish video and pictures, I remove the sd card from the Windows laptop, insert into my Mac, and use "Pictures" app for adjusting color, contrast, etc. No issues.I have tested connecting the camera to my Mac, and it works, but I prefer to use the little laptop at a separate workstation.

Bought this a part of package deal with camera, to use on Amscope trinocular port.While it fits, it is a PITA to use. Focus plane is way off, you have to unscrew microscope port focus almost all the way off, than the worst part is it will not keep focus in sync with eyepieces. If you change the zoom level you will have to readjust one or the other. Ultimately I replaced it with SZMC TV1/2 and couldn't be happier.

Barely fit needed lube to slide the reduction lens in.

Excellent adapter for my microscope
