Broadband Anti-Reflection Coatings

The anti-reflection coating is one of the most popular coatings used on optical components. It reduces the surface reflection and increases the transmission of certain wavelength of light beam. Besides broadband anti-reflection coatings in UV, visible and near infrared ranges, we also provide broadband AR coatings in MWIR and LWIR range.

The standard broadband anti-reflection coatings in infrared range we offer are 3-5 μm, 7-14 μm and 3-14 μm.

The popular substrates we work with are germanium, silicon, ZnSe, BK7 and fused silica. The anti-reflection coatings have excellent bonding to the substrates; and pass humidity, moderate abrasion and adhesion tests.
