TECH SPEC Shortpass filters are available in NIR wavelengths from 750 nm to 1100 nm. These filters are designed to have a very sharp transition from transmission to reflection, making them extremely useful for fluorescence applications, separating spectral orders, machine vision, and creating custom, efficient bandpass filters when combined with color glass longpass filters. With an average transmission of 85% and a blocking optical density of 2.0, high contrast can be achieved. A single layer AR coating on the back surface enhances the overall efficiency of each filter.
