Webcam Eyepiece Mount for Microscopes

Webcam mounts for Bausch & Lomb binocular dissecting scopes.  The mount friction-fits over the eyepiece/ocular and the camera is affixed using zipties (see photos) or velcro strap.

The mounts are specifically designed for a Bausch and Lomb binocular dissection scope with 30 mm diameter eyepieces/oculars; however, I believe most dissecting microscopes are very similar, so the mount should have many applications.  Focus can be adjusted by physically changing the depth of the eyepiece/ocular within the mount.  Once set, you should not need to make any more changes to the mount; the focus adjustments on the microscope and in the camera's software should work well.

Any rectangular webcam with a centered lens should work.  Cameras with off-centered lens will need to be figured out.  See photo.

The depth of field is quite low (see photomicrographs; not stacked).  You can take stacks of photos at different focal depths and just ImageJ to create a composite photomicrograph that appears to be all in focus.

I originally designed and printed these mounts in 2013/2014 for my undergrad research geology projects as a very inexpensive alternative to off-the-shelf options.  Models in photos were printed on a Makerbot Replicator 2 with PLA at 0.1 mm resolutions.  I remember it taking hours; should take less than an hour on a decent printer today.
