Andover Corporation 375nm Steep-Edge Long Pass Filter, 50.0 x 50.0mm sq.

Our steep-edge long pass filters employ magnetron sputtered hard oxide coatings to yield deep rejection and a sharp transition to very high transmission. The coatings are deposited on precision polished Fused Silica substrates, and do not employ any absorbing filter glasses, making them suitable for high-temperature applications. They are offered in three standard sizes, with custom sizes available on request. For less-demanding applications, please see our standard edge filters. BENEFITS Provide very steep (≤1%) cut-on slopes Suitable for high-temperature applications Can be cut or machined to smaller sizes Useful for redirecting a particular band of light COMMON APPLICATIONS Fluorescence Photometry Color enhancement and combining laser studies Show More Information
