Laser-line filters with unprecedented transmission –
pass the laser line and block the laser noise!

Compact and affordable MaxLine thin-film filters offer the following unique advantages:
  • Highest transmission exceeding 90% at the laser line – stop wasting expensive laser light!
  • Rapid roll-off to an optical density > 5 at wavelengths differing by only 1% from the laser wavelength – give your laser >> 50 dB side mode suppression!
  • Negligible temperature dependence for maximum temperature range
  • Hard dielectric coatings for proven reliability and durability
  • Rejected light is reflected for convenient spatial separation
  • UV laser-line filters for 248.6 and 266.0 nm!
MaxLine laser-line filters have the highest transmission combined with ultra-fast roll-off for the most discriminating noise rejection – performance so exclusive that MaxLine  filter technology is patented (U.S. patent # 7,119,960).
