We specialize in optical thin-film coatings, serving a wide range of industries such as the Medical, Aerospace, Defense, Optical Instrumentation, Inspection Equipment, Telecommunications, Imaging, Displays, Lighting & Scanning, Laser and Semiconductor fields.
The enhanced aluminum design provides a better performance than protected aluminum coating. It averages about 94% reflection in the visible spectrum. The coating incorporates the use of a dielectric stack on the aluminum which provides a better resistance to abrasion than the raw metal.
High reflectors, sometimes referred to as laser mirrors, are used when a very high amount of light is needed to be reflected. They typically reflect between 99.0% to 99.995% with scatter as low as 50ppm. The angle of incidence and the center wavelength can be optimized from 0 to 70 degrees, and between 193nm and 3000nm. This type of coating does not usually provide a wide range of performance. Our most commonly produced designs are at 248nm and 308nm, at 0 and 45 degrees incident angles, along with all other major laser lines.
Also known as color filters, these are custom designed to customer specifications. Usually coated with dielectric materials for maximum efficiency.
The V-coat series offers the best single wavelength performance of any anti-reflection coating. It’s design is relatively narrow, which limits the coatings effectiveness if a broader wavelength range or a wide angle of incidence is required. The coating can be applied and optimized for the same index range as the broadband anti-reflection coating. It will provide < 0.25% reflection at the center wavelength.
These ion beam sputtered coatings have extremely low scatter qualities and can provide as low as 10-3 to 10-4 reflection at the center wavelength. They are also applied at ambient temperature which allows more options with regard to tooling and other special requirements.
This coating offers a good performance over a moderate spectral region. When using metallic beamsplitters we do not recommend using high power lasers due to the absorption in the metallic film.
