Aluminum-Coated Mirror
UV-enhanced aluminum reflector: The outer layer of the aluminum reflector is coated with a MgF2 protective layer, which enhances the reflectivity of the ultraviolet band and has a reflectivity of greater than 90% in the wavelength range of 250-450nm. And the protective layer of MgF2 can also protect the strength of the aluminum film and extend the service life of the reflector. Protect the aluminum reflector. Coating the outer layer of the aluminum reflector with a SiO2 protective layer can greatly protect the strength of the aluminum film and is suitable for long-term use in industry and laboratories

Overview
UV-enhanced aluminum reflector: The outer layer of the aluminum reflector is coated with a MgF2 protective layer, which enhances the reflectivity of the ultraviolet band and has a reflectivity of greater than 90% in the wavelength range of 250-450nm. And the protective layer of MgF2 can also protect the strength of the aluminum film and extend the service life of the reflector. Protecting aluminum reflectors. Coating the outer layer of aluminum reflectors with a SiO2 protective layer can greatly protect the strength of the aluminum film and is suitable for long-term use in industry and laboratories. The average reflectivity of protective aluminum reflection is greater than 90% in the wavelength range of 450 nm to 2000nm, and the average reflectivity in the wavelength range of 2 to 20µm is greater than 95%. Characteristics of aluminum-coated mirrors: Flat reflection characteristic curve, wide wavelength range, high reflectivity, and low price. Reflectivity is less affected by changes in wavelength and incident angle. The mechanical hardness of the film surface is not high. The protective aluminum film (Al+MgF2) can be cleaned with a cotton swab containing organic solvents, but the pure aluminum film (ordinary aluminum film) is relatively soft and cannot be wiped. It needs to be replaced regularly. It is not suitable for strong lasers and can be customized according to the specific requirements of the customer
