Polarizer

Its working principle is to selectively filter light from a certain direction. By filtering out a lot of polarized light in diffuse reflection, the intensity of light in the sky is reduced, the sky is darkened, and the contrast between the blue sky and white clouds is increased. When looking at the actual shot, look at the viewfinder and rotate the front mirror. In the viewfinder, the effect is most obvious when the sky is darkest, and the difference between the darkest and the most appearance is 90 degrees. You can turn to any angle between the darkest and brightest according to your needs.

Polarizers are lenses manufactured according to the principle of polarization of light, which can exclude and filter scattered light in the beam, prevent ultraviolet rays and filter polarized light. A good polarizer can achieve the color of the surrounding environment without distortion, the edges of the object are clear, can effectively identify different color signal lights, and reduce the role of ultraviolet rays irradiated into the pupil.

According to the different mechanisms of filtering polarized light, polarizers can be divided into circular polarizers (CPL) and linear polarizers (LPL). The products we produce more are CPL mirrors, which can produce circularly polarized light (positive When in use), the polarizer for circularly polarized light (when used in reverse) can be checked. It is mainly used to suppress the strong reflection (polarized light) on the non-metallic surface, reveal the original color and texture of the object, while increasing the color density, deepening the blue of the sky, highlighting the white clouds, and also reducing the atmospheric fog caused by landscape photos Soft focus, which does not change the tone balance of the entire picture, is the most common efficiency filter.

Common application equipment: UAV lens, photography lens, sports equipment lens, 3D glasses, imaging system, laser instrument, etc.
