Knight Opticals Front-Surface (FS) λ/10 Mirrors for Spectrometers

07 Nov 2019

Knight Optical is a trusted name for on-spec, premium-quality optical components, such as Front-Surface (FS) λ/10 Mirrors, for high-precision spectrometer applications. Our stock and custom-made FS λ/10 Mirrors are offered in a range of material options for such applications; these include BK7 (or equivalent), Zerodur, Quartz, UV Fused Silica; plus many more substrate options.  We can also provide FS λ/10 Mirrors on Convex, Concave and Plano surfaces – as well as large flat or spherical options.

 Manufactured from low-expansion glass for optimum stability and to maintain λ/10 flatness, our F/S Mirrors are capable of delivering high-quality imaging thanks to a higher surface flatness. What's more, they can also be coated to ensure maximum performance with your specified wavelength. Our coatings for FS λ/10 Mirrors include:

 Enhanced aluminium (94%R) for visible applications

  • 99.9% dielectric for laser use in visible applications
  • UV aluminium for ultraviolet (UV) applications down to 180nm
  • 98.5% dielectric for laser use in near-infrared (NIR) applications
  • Ion-plated silver for near-infrared (NIR) 2000nm applications
  • Protected gold for 750nm to far-infrared (FIR) applications.

 Typical Specs (Stock):

Material: Soda-lime float glass

Diameter: +0 /-0.2 mm

Length/Width:  ±0.1mm

Thickness: +0.1 /-0.2mm
