OPTO Photonic

Custom Optomechanical solution which allows users to position a focused laser spot with extreme precision.

​

When probing, a laser point is isolated over a wide-spanning surface area enabling precise, pixel-level measurements across a broad wavelength range.

​

The 10X optical zoom allows precision sample observation and spot location. 

​

Example specifications for a custom designed probe test cell.
