TECHSPEC® λ/4 First Surface Mirrors feature a high reflectivity coating deposited on the front surface of the glass substrate. The coated surface should be oriented to reflect incident light. TECHSPEC λ/4 First Surface Mirrors are offered in circular, square, and rectangular dimensions. First surface mirrors are ideal for applications requiring the mirror to be mounted at 45° in order to produce a 90° bend in the light path. These first surface mirrors easily mount into a range of optical mounts to facilitate application integration. The mirrors have available coatings of enhanced aluminum, protected aluminum, protected silver, and protected gold.

Note:  A range of mounts specifically compatible with individual TECHSPEC® First Surface Mirrors can be found on product web pages.    

Coating Curves

  • Enhanced Aluminum (450-650nm)
Only 2 different Y Axises can be displayed at one time.

Please note that coating performance outside each product’s specified design range is theoretical and may vary.
