The first prototype of a Wi-Fi enabled microscope created for Zoon. We engineered the optics and electrical system, and designed the mounting and housing.
Inspection lens
This is an example of a custom projection lens.  It is F/2 and has a C-mount thread.
Laser Scan Lens
One customer needed a custom laser scan lens for an existing system with a Nd:YAG laser. The picture shows the lens with a one foot ruler for scale.
45° Conoscopic Lens
If you need to measure BSDF quickly, you need a conoscope. It can also enable measurement of the angular distribution of light that is produced by a means other than scattering.
60° Conoscopic Lens
Although stepping up from 45° to 60° with the same camera gives you less resolution, sometimes the increased angular coverage is worth it. If you need an 80° conoscopic lens, please visit our Contact Us page.
