475nm narrow band filter

475nm narrow-band filter adopts the technology of all dielectric hard film coating and the principle of dielectric interference. On the basis of highlighting the characteristics of narrow-band filter, the optical performance is independent of the substrate thickness. The narrow-band filter produced by Borisun Optics is more convenient for the built-in instrument imaging system
