Why Does Optical Glass Have a High Degree of Transparency?
As an Optical Domes Supplier , share it with you. Optical glass has a high degree of transparency, a high degree of chemical and physical (structure and performance) uniformity, and has specific and precise optical constants. Glass Optical Domes The image brightness of the optical system is proportional to the transparency of the glass. The transparency of optical glass to light of a certain wavelength is expressed by the light absorption coefficient Kλ. After the light passes through a series of prisms and lenses, part of its energy is lost by the interface reflection of the optical parts and the other part is absorbed by the medium (glass) itself. The former increases with the increase of the refractive index of the glass. For high-refractive-index glass, this value is very large. For example, the light reflection loss of one surface of counterweight flint glass is about 6%. Therefore, for an optical system containing multiple thin lenses, the main way to increase the transmittance
