Anti-reflective (AR) coatings

Coating facility produces different types of AR coatings: single wavelength, dual-band W-shaped, 3-band and broadband coatings.

• AR coating @ 900-1000 nm for fused silica

Dielectric mirrors

Mirrors can be designed with any required level of reflection from 99.99% to 0.5%. Different type of glass, silicon, can be used as a substrate.

Coatings for laser components

We have delivered a lot of laser-grade coatings to NTHU, NCU, NYCU, KTH (Sweden), and companies. The use of them covers different lasers, including Nd:YAG laser, Ti:Sa laser, He-Ne laser, diode laser, Yb laser, fiber laser, etc. It can be windows, lenses, mirrors, output couplers and other components.

• HR @ 1342 nm, HT @ 1064 & 808 nm
