In addition to tradeoffs between mirror reflectivity, wavefront, laser-damage threshold, and cost, new low-stress coatings offer weight, geometry, and thermomechanical performance and design flexibility.  

The use of high-power continuous wave (CW) lasers in the emerging directed energy (DE) market has put greater emphasis on the quality of optical coatings.

One third of the exchanged final turning mirrors on the National Ignition Facility have been laser damaged by 3ω (351nm) target backscattered light. The mirrors are spectrally complex hafnia and …

Learn how increasing oxygen partial pressure during deposition improves film stoichiometry, absorption, and laser-induced damage threshold (LIDT) at 351 nm.

Completing our suite of deposition equipment, we are developing a new Ion Beam Sputtering (IBS) System with different substrate configurations.

Space can be a harsh environment for optical coatings. Optimax has successfully provided antireflection (AR) coatings for a wide range of space applications.

Every optical application requires a “clean” optical surface. However, what defines “clean” is subjective and is based on the needs of the application.  

There are many decisions to make when designing, specifying, manufacturing, and testing optical components for high-energy laser systems — each is a potential failure mechanism that must be understood and …

Optimax has developed a novel optical coating (OTR‐AR). OTR coatings have been demonstrated to provide excellent resistance to latent scratching, staining and dimming of chemically sensitive optical glass surfaces in …

Design, specification, and procurement of optical coatings all benefit when the designer has a good understanding of measurement techniques and uncertainties.
