WebMost types of Ohara optical glass are transparent and colorless because they are made of very pure materials. However, some optical glasses show remarkable absorption of light near the ultraviolet spectral range. For certain glasses with extreme optical properties, such as high refractive index, absorption extends to the visible range.

Thermal and optical properties of PMMA films reinforced with Nb
http://www.oharacorp.com/o2.html While most industrial glasses report optical properties as external transmittance, values for filter glasses are typically given as internal transmittance. This is because filter glasses may be treated with anti-reflective coatings to prevent intensity losses at the glass surface. See more You’re probably familiar with the concept of “traveling at the speed of light”, but did you know that the speed of light can change? Light’s speed is reduced when it travels through a … See more When light travels through a glass, the intensity of the light is typically reduced. This absorption happens when the energy of a photon of light … See more It’s important to note that all of the optical properties previously outlined are wavelength dependent. For example, the refractive index of a … See more Any light that is not absorbed by a glass or reflected at its surface will be transmitted through the glass. It is often very important to know exactly how much light will pass through a … See more iphone13指纹开机
