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.
- Analyzers for clinical chemistry
- Various process controls, e.g. during grain harvest
- High edge steepness
- High blocking and transmission
- High temperature stability
- Cut-on / cut-off wavelengths from 400 nm to 1000 nm
- Blocking up to DUV (long pass filter) or 1200 nm (short pass filter)
