The difference is clear….

MATE PEAK™….the low absorption, high performance laser lens for demanding applications or high power cutting.

NEW MATE PEAK™ Lens offers the latest technology for CO2 laser cutting:

  • Low absorption for maximum cutting power.
  • Improved cut quality and consistency.
  • Helium Neon (HeNe) laser beam compatible for safer laser operation.
  • Proprietary clear coating offers superior lens stability and allows for lens inspection and stress analysis.


Absorption is a key determinant of CO2 laser lens life. Conventional coatings absorb significant thermal energy in normal laser operation. Over time, the accumulation of processing residue further increases lens absorption.

Due to the extreme energy of a laser beam passing through the lens, even very small changes in absorption will result in thermal effects in the lens-such as a shift in the size or location of the focal point-and subsequent deterioration of the cut or kerf quality.

Due to its low absorption levels, the Mate Peak™ Lens offers:

  • Higher power handling capacity-to 6000+ watts.
  • Better cut quality performance.
  • Longer optimal performance (with regular cleaning and maintenance).

Mate Peak™ vs Standard AR Coating


Compared with standard lenses, Mate's Peak™ low absorption coating results in more stable operation due to reduced thermal effects and less focal plain variation. The bottom line? Better cut quality and more consistent parts production.
