Abstract

It is known that the UV narrow-band filters are important in the specific application. In this paper the design and the fabrication of a series of narrow-band filters for sequential central wavelengths from 300 to 380nm are reported. The technical requirements of the filter designed are as follows: ■ Center-wavelength distance between every two filters is 5-10nm. Shown as figure(1). ■ The peak transmittance of central wavelength ≥ 40%. ■ The long wavelength rejection zone extends to 690-2500nm (According to different demands). ■ The short wavelength rejection zone extends to 200nm. ■ The transmittance for rejection zone ≤ 1‰.
