Optical Metrology
At Alien Photonics, we prioritize the quality of our optical components with dedication. Each batch undergoes meticulous testing according to our strict quality policy, ensuring that every component is ready for use once delivered. Facing a demanding application that requires specific non-standard measurements? Don't worry—Alien Photonics custom measurement setups are ready to meet your needs.

Additional measurements
Cavity ring down spectroscopy (CRDS)
To evaluate extremely low values of light loss (absorption, scattering). Usually for testing High reflection mirrors (HR>99.95…%).
Laser Induced Damage threshold (LIDT)
To figure out maximal amount of laser light intensity an optical component can withstand without damage.
Environmental chamber testing
To test components performance in various temperatures and humidity levels (simulate real-world conditions).
Adhesion and Abrasion
To evaluate if coating adhesion (how strong the coating is bonded to substrate) and abrasion (resistance to physical contact) complies with standards.
