Deflecting mirror

  • Highly reflective coating for Nd:YAG
  • Coating for high transmission
    • in the visible range from 400 to 700 nm

Protective glasses

To protect the expensive laser optics, many customers in the industrial sector use protective glass (sacrificial glass).

In order to minimise energy losses, all our protective glasses are anti-reflective coated on both sides in the 1064-1070 nm range (or according to your specifications).

In addition, a customised coating can be applied for the pilot laser, e.g. in the 400 to 650 nm range.

We stock the most frequently used protective glasses for Nd:YAG or fibre lasers (e.g. for the laser brands LASAG, Trumpf, Alpha, etc.)
