OPTOMAN’s Enhanced Lifetime IBS-coated Dichroic Mirrors are designed to deliver long-term optical performance, and higher LIDT in demanding laser applications. Non-Degrading Technology enables lower maintenance costs and reduced downtime, making it a smart, reliable choice for industrial, medical, and scientific UV laser systems.

These filters are optimized for reflecting 343 nm at a 45° angle of incidence, and transmit 515 nm and 1030 nm featuring an extended operational lifetime, even under continuous high average power or high repetition rate exposure.

With reflectance for III harmonic and transmittance for I and II harmonics, this filter is optimized for Yb:YAG based ultrafast laser systems.

Advantages of this product compared to other solutions in the market:

  • No color-change effect
  • Enhanced lifetime (over 10000h)
  • Higher LIDT (>0.35 J/cm² @ 343 nm, 300fs)

The technology directly translates into lower maintenance costs and reduced downtime.

 Products marked with this tag are SuperHero Tier products. They possess the best capabilities of OPTOMAN and make our R&D department proud.
