Knight Optical’s λ/10 Mirrors for Aerospace Governmental Testing

25 Oct 2020

Commonly used in cutting-edge aerospace governmental testing applications, our premium Front-Surface (FS) λ/10 Mirrors are widely employed for high-specification projects. With exceptional flatness, Knight Optical FS λ/10 Mirrors have several capabilities; but are mainly known to allow for greater signal quality, resulting in higher quality imaging – ideally suited to government testing applications. 

 We understand the importance of on-spec, high-quality components; particularly within discerning industries such as the Aerospace division. Consequently, we offer our components as custom-made optics, allowing you to specify project-specific dimensions, tolerances, coatings and substrates, such as BK7 (or equivalent), Zerodur, Quartz, UV Fused Silica; plus many more material options. What's more, for projects seeking quick turnaround times, we also stock a wide range of FS λ/10 Mirrors, available for next-day dispatch. 

 Manufactured from low expansion glass to achieve the sought-after lambda/10 flatness, our FS Mirrors assist in producing high-quality images and are available in Convex, Concave and Plano varieties. Furthermore, we also offer an optical coating service allowing you to choose from our wide array of options to ensure perfect quality imaging and specified wavelength is delivered. Such coatings 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 the near-infrared (NIR) applications
  • Ion-plated silver for near-infrared (NIR)-2000nm applications
  • Protected gold for 750nm to far-infrared (FIR) applications.
