Low Absorption Coatings on Micro-Optics


Micro-optics are optical systems that are between a few micrometers and a millimeter in size. Small items like that are difficult to handle throughout the whole coating process, but OPTOMAN has made investments in equipment enabling repeatable process and the experienced and precise OPTOMAN squad has proven that no optics are too small for them to handle.


Now micro-optical systems can be built with IBS coated components with low absorption transmissive coatings, which pushes the overall efficiency to the new levels. For example, low absorption IBS coatings on fast axis collimators (FAC) minimize the unwanted effects originating from the heat generated by the laser diode.


Absorption loss <1 ppm per coated surface @ 1064 nm

Absorption is the main damage and fatigue driver. With absorption being at low level, AR coated Micro-0ptics feature enhanced duty cycle.

Reflectance per surface down to R<0.01%

Sputtered anti-reflective coatings feature performance close to theoretical

High Laser-Induced Damage Threshold

OPTOMAN transmissive coatings can be optimized for high LIDT and feature values of >40 J/cm2 @ 1064 nm, 10 ns, 10 Hz, S-on-1.

Temperature and humidity independent performance

Durable, non-porous and near bulk IBS coatings increases the longevity and reliability of Micro-optical system, eventually resulting in a lower total cost of ownership.
