Introduction to Colored UV Glass for UV Filter Classification
1. Basic understanding of UV filters (UV lenses or UV glass):
Long wave ultraviolet light refers to ultraviolet light with a wavelength between 320 nanometers and 400 nanometers, which has strong penetration ability and can penetrate glass. Its energy is equivalent to most chemical bond energies, and it is easy to induce photochemical reactions. This is the type used for photo curing.
Medium wave UV-B, with wavelengths between 280-320nm, has weak penetration and is strongly absorbed by glass. Sunlight contains abundant UV-A and UV-B
Short wave UV-C, with wavelengths between 200-280nm, is strongly absorbed by the ozone layer, so solar UV-C is absorbed by the ozone layer between the ground and the sun. UV-C has a strong destructive effect on living organisms, killing bacteria and viruses, and is therefore commonly used for disinfection.
UV lenses, UV transparent lenses, and UV transparent glass mainly include the following types: UV glass, UV transparent glass, and UV transparent glass.
Product Name: UV Glass, UV Filter, UV Transparent Glass, UV Glass, UV Transparent Glass, UV Glass.
The product color is colorless transparent glass and black non transparent glass.
Conventional thicknesses of 2mm, 3mm, 4mm, 5mm, etc
Processing technology includes tempered heat treatment, non tempered heat treatment, and semi tempered heat treatment.
In terms of application fields, UV transparent glass is mainly used for address surveying, non-destructive testing, UV sterilization, UV antivirus, UV drying and other fields.
2. Classification of UV Glass
UV transparent glass is divided into two types: investment grade black glass and UV transparent glass.
UV transparent black glass: The product is divided into long wave UV transparent glass, short wave UV transparent glass, and bandpass UV transparent glass, with transmission wavelengths of 254nm/310nm/365nm respectively. This type of glass has good UV transparent performance and can filter out visible light.
UV transparent glass: It is a colorless cutoff glass with a wavelength range of 220 nanometers to 380 nanometers and a transmittance greater than or equal to 90.5%. Ruicheng Optoelectronics has also launched a far ultraviolet glass that is transparent in both the UV and visible spectra, with strong absorption bands in the 2600nm-2800nm wavelength range and no absorption bands in the 185nm-260nm wavelength range. It does not emit light and has stable radiation.
