High Transmission UV Bandpass Filters

Graph High Transmission UV Bandpass Filters
  • 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 performe yielding the maximum brightness and contrast in any UV application.
