System Assembly Troubleshooting / Light leakage in miniscope body
« on: December 06, 2017, 02:11:09 AM »
Hi everyone,
I have recently assembled miniscopes and had light leakage problem, which was not detected in the miniscopes I assembled last year.
Applying black enamel paint on the filter edges helped a little but I can still see some light coming in to the CMOS sensor when I put the scope on black surface.
I confirmed that the CMOS sensor and LED parts have nothing to do with the light leakage by swapping the parts with my older miniscopes... It seems that the problem is solely coming from the body(where achromatic lens and filters go in).
The biggest difference between my older miniscopes and new miniscopes is that the inner diameter of the hole where the acromatic lens sits on. The new scopes have much bigger inner diameter than the previous ones. Could it be causing the problem?
Attaching pictures would helped but I couldn't figure out how to upload image files so I tried my best to describe the situation by word...
Thank you.
