Shortpass Filters can be used with Longpass Filters to create custom bandpass filters to selectively transmit portions of the spectrum while rejecting all other wavelengths. Shortpass Edge Filters can ...

Usually this is a band-pass design with 30–60 nm ... any light transmitted through the excitation filter. This blocking is typically measured in optical density (OD), which is the negative ...
