Hard coat broadband filters
From AndoverOur first-surface, hard-coat, broadband 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 standard Raman wavelengths: 488, 514, 532, 633, 785nm. We offer three standard sizes, with custom sizes available on request.
