What are the optical materials commonly used in filters and optical lenses?
2024-12-17
In modern optical systems, the formation of light paths relies on optical refractive elements and optical reflective elements. The optical wavelength range of modern optical systems covers a wide spectrum, so when we produce filters and lenses, we also select high-quality optical materials based on different optical wavelength ranges to design and manufacture filters and optical lenses.
Optical components such as filters and optical lenses are made from optical glass. Generally, common optical glass can transmit light with wavelengths ranging from 0.35um to 2.5um, while light beyond this range will be strongly absorbed by the optical glass. Therefore, when designing and producing filters and optical lenses, special unconventional optical glass materials are selected to transmit specific wavelength ranges.
So what are the commonly used optical materials for filters and optical lenses?
Shenzhen Nahong Optoelectronics introduces some commonly used optical materials to provide reference for your design and production of filters and optical lenses.
The list of common optical materials for filters and optical lenses is as follows:
Optical grade glass: Crown glass, flint glass, and various colorless optical glasses.
Ultraviolet band optical grade glass: UV fused quartz, calcium fluoride, magnesium fluoride, etc.
Infrared band optical grade glass: Infrared fused quartz, calcium fluoride, magnesium fluoride, gemstones, silicon, germanium, zinc selenide, etc.
Crystal optical grade glass: Ice stone, YVO4, quartz crystal, lithium niobate, a-BBO, etc.
