Narrow band filters are fabricated by using advanced deposition process technology-Ion Assisted Deposition (IAD). This process produces highly dense, environmentally stable and durable thin films, which prevent drift of filter's peak wavelength with age. To improve the pass band energy and increase the attenuation in the blocking band, HHV introduce more cavities into the construction of our band pass filters.
