IR Fused Silica Optical Hot and Cold Flat Mirror with Multi-Layer Dielectric Coating

Several kinds of coatings are available The broad bandwidth mirrors are enhanced aluminium coated under a layer of. Sio2 protective film. The reflectance peaks at about 95% and the wavelength range from visible to FIR(0.35-12μm).Furthermore the metallic coating is not angle-sensitive. The laser line mirrors are multilayer dielectric coated, optimized for the preferred wavelength and incident angle. The central wavelength, incident angle and coating requirements should be specified at placing an order. These mirrors can be ordered with or without mountings.

Cold mirrors reflect visible light while allowing IR light pass through but not using it.Cold mirrors are ideal for illumination systems where high temperature lighting is not desired. Hot mirrors reflect harmful IR waveband which can produce heat, while allowing visible waveband to pass through.

Features:Transmit Visible or IR,Reflect IR or Visible.

Applications:IR-Filters, Lighting System,Applied mainly in projection and illumination systems.
