Description

High performance longpass filter features high transmission in the pass band combined with superior blocking in the rejection band. With a rejection band optical density of 4.0 combined with >91% in the pass band these filters are ideal for a wide variety of applications. Eliminate stray light by creating custom bandpass filters when combined with hiigh performance shortpass filters.
