Description
Tempotec supplies custom dielectric and metal-coated mirrors from the deep UV to the far IR. Dielectric high-reflection mirrors reach over 99% average reflectance from 200 to 2600 nm at angles of incidence from 0° to 68°. Metal-coated mirrors in aluminum, silver and gold cover 250 nm to 20 µm for broadband use.

Frequently Asked Questions
Should I choose a dielectric or metal mirror?
Dielectric mirrors give the highest reflectance (> 95%) over a set band, ideal for lasers. Metal mirrors reflect over a much wider range at somewhat lower reflectance.
Which metal coating suits my wavelength?
UV-enhanced aluminum for 250–450 nm, protected silver or aluminum for visible to IR, and gold for 800 nm to 20 µm.
What angles of incidence are supported?
Dielectric mirrors can be designed for any angle from 0° to 68°, including 45° for beam folding.
What is the difference between protected and unprotected gold?
Unprotected gold reflects slightly more (> 97% vs > 96%) but is soft and easily damaged; the protective layer allows cleaning and handling.
What should I specify for a quote?
Mirror type, wavelength range, angle of incidence, polarization, size, substrate, surface flatness and quantity.
