WebJun 15, 2024 · These mirrors offer >90% average reflection in the spectral range from 450 nm - 2 µm and >95% average reflection in. the spectral range from 2 - 20 µm. They consist of an aluminum-coated N-BK7 substrate that features a protective SiO 2 overcoat. With ≤λ/4 surface irregularity at 633 nm, these mirrors provide excellent image quality. WebAn Introduction to Optical Coatings. This is Sections 11.1, 11.2, and 11.7 of the Laser Optics Resource Guide. Optical coatings are used to enhance the transmission, reflection, or polarization properties of an optical component. For example, about 4% of incident light will be reflected at each surface of an uncoated glass component.

Webspecular reflection. All polished and smooth surfaces reflect light as a mirror. Usually mirrors are a combination of a glass pane, which can be made very flat and smooth, coated on its back by a reflective metal layer. All materials, even the most insulating and transparent ones, such as uncoated glass, reflect light, at least to some extent. WebPartial and high reflectivity optical mirrors are available directly from stock in narrowband, dual-band, and broadband spectral profiles on flat, wedged, or curved substrates using a variety of robust dielectric and metal coatings, designed for 0° or 45° angle of incidence at wavelengths from 190 nm to 2000nm. bohn hyundai
