NIR-TRANSMAX™ – AR Coating for a Broad NIR Range

Ultimate Efficiency for NIR Sensors and Optical Network Devices

NIR-TRANSMAX™, (Near Infra Red) a Materion Balzers Optics product, is a broadband multilayer AR (antireflection) coating. It is designed to exhibit lowest reflection in the range from 1250– 1650 nm (S-, C- and L-band range) simultaneously. It reduces the insert loss to R < 0.1% (–0.005 dB) and guarantees an ultimate efficiency for NIR applications such as sensors and Optical Network Devices.

Benefits

Concept for mass production and logistics
Non polarizing
Ultimately low insert loss R < 0.1% (- 0.005dB)
Covers the S-, C- and L-band simultaneously
Absorption free
Excellent environmental resistance

Applications

Cover glass of optical devices
High quality instrument
Lenses from (ø1 to ø10 mm)
