Optical mirrors are precision optics with a highly polished plane or curved surface which reflects light.  At Shanghai Optics we manufacture custom optical mirrors for a wide range of applications. Life Sciences, astronomy, metrology, and solar engineering are only a few of the industries which depend on our precision mirrors and other optical components.

Our state of the art machinery allows us to manufacture high quality mirrors designed to reflect a certain wavelength range while allowing light transmission in other wavelengths. Custom optical mirrors and precision reflectors can also be designed to reflect at pre-specified angles.

Front Surface Mirrors for Superior Imaging

All mirrors can be categorized as second surface or front surface mirrors. A second surface mirror is a standard mirror with the coating on the back side of glass or other transparent material. A front surface mirror, with the reflective coating on the front side, gives a more exact reflection with no double image. These mirrors are often a good choice for engineering applications because of the accuracy of the reflected image.

Hot Mirrors and Cold Mirrors

Hot and cold mirrors are both specialized dielectric mirrors which are used for heat control; to filter unwanted energy from a light source.  A cold mirror will reflect 90% of the visible light spectrum while efficiently transmitting (and thus removing from the site of interest) infrared wavelengths.  A hot mirror will reflect 90% of infrared and near infrared light, and transmit a large portion of visible light (up to 80%).  Shanghai Optics can manufacture hot and cold mirrors for any angle of incidence desired, from 0 to 45 degrees.
