Andover's steep-edge (1% slope) long pass filters employ magnetron sputtered hard oxide coatings to yield deep rejection and a sharp transition to very high transmission. They are deposited on Fused Silica substrates, and do not employ any absorbing filter glasses, making them suitable for high-temperature applications. Offered in three standard sizes, custom sizes available on request. Read more...More Product Announcements from Andover Corporation
