Alluxa - Ultra-Narrowband Optical Bandpass Filters

LASER COMPONENTS is pleased to announce ultra-narrowband filters from Alluxa. These offer the narrowest and “squarest” filter profiles in the visible and NIR with very high transmission levels typically greater than 96%.  

Unlike narrowband filters made with other deposition technologies, these ultra-narrowband filters offer wide and deep blocking performance at levels up to and beyond OD6 without sacrificing transmission performance. This is a result of the sophisticated monitoring and deposition methods, which produce a hard coating with temperature stability and out of band blocking, far superior to that of legacy soft coatings. Narrowband filters are now fully customisable and able to achieve exceedingly narrow bandwidths at very discrete wavelengths of light.
