Factory Custom Blue Optical Filter Glass QB29 BG25 B-380 For Fire Watch Glass
The filter is made of glass and special dyes. The blue filter can only let blue light pass through. Compared with ordinary glass, the molecular structure and refractive index of blue filter have changed, and the passage of some color light has changed. For example, when a white light passes through a blue filter, it emits a blue light, while the green light and red light are very few, and most of them are absorbed by the filter. The filter plays a very important role. It is widely used in photography.
