Hard-Coated Narrowband Filters

Name: Hard-Coated Narrowband Filters
Brand: Andover Corporation
Availability: InStock

Description

Our Hard-Coated Narrowband Filters are high-quality optical filters that employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass, providing a steep transition from high, peak transmission to OD4 blocking.

These filters are suitable for high-temperature applications and are available at wavelengths from 334nm to 1550nm, including all major laser lines and atomic absorption lines. They are mounted in black anodized aluminum rings for protection and easy identification.
