Spherical Mirrors

Spherical Mirrors

  • Chromatic aberration free for concentrating, collecting, and imaging applications
  • Aluminum overcoated with MgF2 for high durability
  • Polished rear surface for easy mounting
  • Standard diameters from 15 to 50.8mm

 

These mirrors are used for laser beam concentration and quality imaging. They can also be used to improve the light output from projection and illumination systems. All spherical mirrors have a focal length equal to half their radius of curvature. The front concave spherical section is polished on a BK7 substrate and then coated with aluminum and MgF2.

 

Mirrors are offered in several sizes with a wide range of curvatures from 10mm to 4m. Other diameters, diameters greater than 50.8mm, and other radii of curvature are also available. Please call.
