High Transmission UV Bandpass Filters

Asahi Spectra

產品特色
  • High transmission and high rejection in UV wavelengths
  • 10nm FWHM
  • Will not autofluorescence
  • Excellent thermal resistance

Our high transmission UV filters set the new standard in UV bandpass filter performance and reliability. These filters achieve >60% - 70% transmission at the UV wavelengths from 254nm - 390nm, and offer blocking of OD3.0 (0.1%) at the rejection bands.

One of the unique feature is that rejected light is reflected instead of absorbing, easing stray light management issues. Our high transmission UV filters provide you to simplify system setup. Each filter performs yielding the maximum brightness and contrast in any UV application.
