  • Crystal coating optical low pass filter and manufacturing method thereof
    Patent number: 10324241
    Abstract: The present invention discloses a crystal coating optical low pass filter, which includes a UV-IR cut-off film, a crystal plate, an ink layer, and an AR film. The UV-IR cut-off film can be replaced with an IR film. By coating the crystal plate with ink having infrared absorbing effect to form an ink layer, the present invention possesses both the birefringence characteristic of the crystal and the effect similar to infrared absorbing glass. Compared with the traditional OLPF using infrared absorbing glass, the thickness of the product is reduced and the situation that the infrared absorb glass is fragile and has a poor resistance to drop is significantly improved. The present invention can be used in smartphones, digital cameras, in-vehicle cameras, security cameras and has a large space of marketing.
