Often referred to as long wave pass (LWP) and short wave pass (SWP) filters, Andover Corporation's sharp-cut edge filters are distinguished by their high rate of transition between their region of reflection and transmission. This high rate of transition makes them an excellent choice as emission filters in fluorescence applications, and as order sorting filters in photometry. Read more...

Andover Corporation's steep-edge 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...
