Product details:

GRB3 is a silicate absorbing glass with the following properties:

- Color: GRB3 glass is slightly blue-green and close to colorless glass.

- Light transmission characteristics: high transmission to visible light and effective absorption of infrared range (especially 1000nm infrared absorption).

- Customizability: Can be customized according to customer needs, including size, shape and thickness.

GRB3 glass is commonly used in the following areas:

- Heat insulation glass: used in cold light source products, such as operating room cold light, slide projector, projector, etc.

- Optical instruments: can be used to manufacture lenses, prisms, mirrors, etc., in optical instruments.

The function and characteristic of filter:

A filter is an optical device used to select the desired radiation band. One of the commonalities of filters is that no filter can make the image of a celestial object brighter, because all filters absorb certain wavelengths, which makes the object darker. Optical filters are very useful and widely used in photography.

Optical filter role: The role of the filter is very large, widely used in the photography industry. Some landscape paintings shot by masters, why is the main scene always so prominent, how is it done? It's because of the filter. For example, if you want to shoot a yellow flower with blue sky and green leaves in the background, if you shoot according to normal, you can not highlight the theme of "yellow flower", because the image of yellow flower is not prominent enough. However, if a yellow filter is installed in front of the lens, the sun blocks the green light emitted by a part of the green green leaves, the blue light emitted by the blue sky, and the yellow light emitted by the yellow flowers through a large number of, so that the yellow flowers appear very obvious, highlighting the theme of "yellow flowers".

Glass filters are made with special dyes, red filters can only let red light through, and so on. The refractive index of the glass sheet was originally about the same as air, and all colors of light can pass through, so it is transparent, but after dyeing the dye, the molecular structure changes, the refractive index also changes, and the passage of some colors of light changes. For example, a beam of white light through the blue filter, emitted is a beam of blue light, and green light, red light is very little, most of the filter is absorbed.
