Frameless Mirrors

Frameless Mirrors

Frameless mounting is designed to minimise footprint space and allows the maximum front surface area of the mirror to be coated. These high reflectivity mirrors are produced using either a ceramic or fused silicon material.

Frameless mirrors with ceramic coating:

  • Surface accuracy guarantee after coating: λ/10
  • 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)
  • The patent related to this product was obtained by SIGMA KOKI CO., LTD. in November 2011

Frameless mirrors with fused silica coating:

  • Surface accuracy after coating: λ/8 (λ/4 guaranteed)

Notes:

  • Reflectance of the specification are represented by the average of the reflectance of P polarised light and S polarised light.
  • If the product is used without setting the angle of incidence to 45 degrees, the reflection rate may decrease.
  • Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
