Frequently Asked Questions

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

The features of Hard-Coated Narrowband Filters include first-surface hard-coat coatings, suitability for high-temperature applications, a steep transition from high peak transmission to OD4 blocking, availability at wavelengths from 334nm to 1550nm, and being mounted in black anodized aluminum rings for protection and easy identification.

Hard-Coated Narrowband Filters are suitable for machine vision, biotech instrumentation, and medical devices.
