Short and long pass filters are also known as edge filters. LASER COMPONENTS offers a wide variety of design options.
By using proprietary 'Quasar' technology, the transition in both SP and LP filters between the 50% cut-off or cut-on to rejection is quite sharp.
Edge filters with very short transitions between stopband and transmission range are used for Raman applications, among others.
Dichroic filters are edge filters for colour separation used under diagonally incoming light.
