Our first-surface, hard-coat narrowband filters employ magnetron sputtered, hard-oxide coatings deposited on Borosilicate Glass and do not utilize any absorbing filter glasses, making them suitable for high-temperature applications.

They provide a steep transition from a high, peak transmission to OD4 blocking. Available at wavelengths from 334nm to 1550nm, including all major laser lines and atomic absorption lines.

All filters are mounted in black anodized aluminum rings to provide protection and easy identification.
