Optics-M offers extensive coating capabilities for optical components operating throughout the ultraviolet (UV), visible, and infrared (IR) spectra. We perform a wide variety of single and multi-layer coatings including broadband, v-coat, polarizing, metallic, and narrow bandpass.

Optics-M  is designer and manufacturer of laser coatings for mirrors, beamsplitters, windows, and other optical components. We work with a number of testing laboratories to independently qualify and certify our coatings for resistance to laser damage. All specified damage threshold values have been obtained by testing multiple coating runs to ensure an accurate result. The values specified are conservative, with typical data showing that our mirrors are able to withstand 2-3 times the specified threshold.

We are able to design and manufacture coatings for single or multiple laser lines, as well as for broadband tunable laser sources. Coatings designs are also available for partial reflectors, output couplers, and etalons, and for any angle of incidence or polarization state. Our world class manufacturing facilities are able to produce substrates with surface accuracies of < 1/20λ, surface qualities of 10-5, parallelism of <0.5 arcseconds, and surface roughness of <5 Angstroms in any glass and most crystalline substrates. We will also coat customer-supplied substrates for prototype or production volumes.

For high-power applications, coating designers choose materials with intrinsically low absorption at the relevant wavelengths. But the customer also needs to be aware that the choice of coating materials for high-power applications is limited. The system-designer does well to design for optics with the appropriate damage thresholds from the beginning of the optical design process.

Coatings for use with high-power ultraviolet (UV) lasers are made of different materials from those for use in the visible and near-infrared (IR). The core structure of high-reflection coatings is typically a repeating stack of high- and low-index layers, each a quarter-wavelength thick. The design of the coating can significantly alter the damage threshold. Simply adding a half-wave of low-index material (normally silicon dioxide) as the final layer can result in measurably higher damage thresholds. Silicon dioxide (SiO2) is the generally accepted and ubiquitous choice for low-index layers, and dielectric metal oxides in general are preferred materials for UV, visible, and near-IR laser applications. Choosing a material for high-index layers is not as straightforward: oxides of titanium, tantalum, zirconium, hafnium, scandium, and niobium are all popular high-index materials.
