Frameless Mirror Unit – Ceramic

Frameless mounting is designed to minimise footprint space and allows the maximum front surface area of the mirror to be coated. Our high reflectivity mirrors are produced using a ceramic material. Thermal expansion ratio is equivalent to Zerodur® for maximum thermal stability.

  • Laser damage threshold of the mirror is equivalent to our high power dielectric laser mirrors (TFMHP).
  • λ/10 surface accuracy guarantee after coating.
  • The patent related to this product was obtained by SIGMA KOKI CO., LTD. in November 2011.
