Custom Optical Coatings

Tower applies high-power laser and specialty thin-film coatings: anti-reflection, reflective, partial reflectors, beamsplitters, polarizers, and dichroic / color-separating coatings, plus metallic aluminum (protected/enhanced), silver, and gold. Wavelength coverage from UV through VIS, NIR, and IR — including laser lines from 193 nm to 10.6 µm. Ion-beam sputtered (IBS) films are available for the most demanding specs, and we can design your optical system and coatings computationally.
