Precision Reflector

Shanghai Optics is a custom optics manufacturer with over 55 years of optics manufacturing experience. We offer custom made Precision Reflector according to customer’s specifications.

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.

Standard sizes are 1 and 2 inch with a wide range of curvatures from 50mm to 4m. Other diameters, diameters greater than 100mm, and other radii of curvature are also available.

Key Features

Chromatic aberration free for concentrating, collecting, and imaging applications
