Edge Filters (Shortpass and Longpass Filters)

Edge filters separate a broad spectrum of light into two components: a transmitted and a blocked component.

These filters are defined by either a cut-on or a cut-off slope, which provides the transition between a high blocking region and a high transmission region. Cut-on and cut-off edges are typically defined by long wave or short wave pass filter coatings.
