Please, note that we are still open at this hard time. One of our labs is located in a single-family residence where some manufacturing and measurements services could be performed complying with a stay-at-home regulation.
Aloha and take care.

We are on the Facebook.
Not much more to say though. Hopefully we will find some sense in that Facebook presence.

sensitivity better than 1 ppm with 100 mW laser source
||Testing optics on demand
Optical materials expertise
|AR coating, 1x1 mm area scan at 532 nm|
|Lava color theme|
|What could be tested:|
- AR, HR coatings. thin films
- low absorption tests (2 ppb resolution reached with 10 W laser source)
- homogeneity of absorption across the surface with up to 5 um resolution
- surface defects and contamination
- Optical materials: glasses, crystals
- bulk absorption tests (0.1 ppm/cm resolution reached with 10 W laser source)
- homogeneity of absorption with longitudinal space resolution up to 200 um
- laser-induced absorption, laser annealing effects
- Laser crystals: Nd:YAG, Nd:YVO4, Ti:Saphire, etc.
- transient and induced absorption
- only thermalized part of absorption is detected
- Nonlinear crystals: KTP, LBO, BBO, LiNbO3, LiTaO3, periodically-poled, etc.
- gray track characterization [KTP]
- induced absorption measurements [e.g. GRIIRA in LiNbO3]
- non-thermal response: photorefraction
- Composite objects: bonded optics, liquid crystals cells, etc.
- tests with IR probe
- non-thermal responses: free carriers effects, photorefraction
- Liquid and gaseous samples
