Knight Optical’s complete range of cost effective bandblocking dichroic filter sets offer superior transmission, reflection and absorption characteristics
Dichroic band blocking filters are designed to block an isolated bandwidth while transmitting all other wavelengths. While traditional glass and interference bandpass filters offer improved blocking characteristics, the advantage of bandblocking dichroic filters comes with the enhanced sharpness of transition between the transmitting and reflecting bands and therefore improved blocking accuracy. Having negligible absorption they are suitable for high powers and do not show the strong fluorescence of certain glass filters.
Our dichroic bandblocking filters are available in a range of wavelengths and are supplied in standard 12.5mm and 25mm diameter or 50mm square types. We are happy to cut and edge filters for non standard sizes to suit your application.
Wavelength cut-on listed in table is transition cut-on wavelength (T=Tmax/2)
Available size: Square 7mm-300mm, Diameter 10mm-400mm
Cutting down or edged to special shapes and sizes at short notice
