Raman edge filter sets
What are you looking for in Stock?
Knight Optical supply precision quality custom edge filters for use in Raman spectroscopy or confocal microscopy applications. These filters are designed to exhibit sharp transitions between the low, blocked wavelengths and the Raman signal transmissions to ensure excellent accuracy when undertaking testing. Custom edge filters typically give high blocking of low wavelengths down to 200nm and beyond, and greater than 95% transmission beyond the cut on point to improve detection of weak signals with hard coatings demonstrating improved transmittion and durability over a similar soft coating.
Longpass edge filters are not sold as a stock item. Knight Optical offer an extensive custom optic service thanks to our many years experience in this field.
In addition to individual filters, we are able to supply edge filter sets containing multiple bespoke filters presented in an attractive wooden box for safe storage. More information can be found by contacting our technical sales team directly.
