Dielectric NIR coated mirrors offer maximum reflection over a broad spectral range.

Low absorption is maintained with a dielectric multilayer coating using high transmittance glass material and can be resistant to a rapid change in high temperature. Their coating is more durable, making them easier to clean, and more resistant to laser damage.

Cold Mirror coatings can be used as a NIR filter by changing the angle of incident.
