UV Fused Silica Precision Optical Flat Metallic Mirror with Enhanced Aluminum 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.
Standard metallic mirror coatings include Protected Aluminum, Enhanced Aluminum, UV Enhanced Aluminum, Protected Gold and Protected Silver. Protected Aluminum and Enhanced Aluminum are typically used for visible applications. UV Enhanced Aluminum can be used for UV and visible applications. Protected Gold offers high reflectance for Infrared or near-Infrared wavelengths. Protected Silver provides the highest reflectance between 500-800nm but is best suited as a rear surface reflector due to its sensitivity to tarnishing
Features:Narrow Band and Broadband Wavelength are available,Low Cost.
Applications:Sensors,Projection Systems,Ideal for Far Infrared Laser Applications.
