Ultra-narrowband filters

Laser Components now offers Alluxa’s ultra-narrowband filters, which the company says are the narrowest and ‘squarest’ filter profiles in the visible and near-infrared (NIR) with transmission levels typically greater than 96 per cent. 

Unlike narrowband filters made with other deposition technologies, these ultra-narrowband filters deliver 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, superior to that of legacy soft coatings. 

Narrowband filters are now fully customisable and able to achieve narrow bandwidths at very discrete wavelengths of light.
