Changchun Realpoo Photoelectric Co.,Ltd.
Fresnel lens used in the projection system, its role is to collimate light and focus light.
Fresnel lens will be the light source to retrieve the beam light source mobilization for parallel light, apparently improve the brightness of the panel around, eliminating the sun spot effect.Eliminate the sun spot effect, so as to improve the overall brightness uniformity. General Fresnel lens and the rest of the components (such as column mirrors) together.
Fresnel lens used in the advantages of the projection system: after focusing or mobilization of light collimation so as to increase the brightness of the body appears.
If the collimator is eliminated, light will be lost through the panel, appearing in the obvious hot spot effect, increase the brightness of the screen around.
Similarly, on the other side of the LCD screen, it is necessary to collect the light from the panel to the projection lens.
Realpoo Optics can customize different size, shape and focal length of Fresnel lens for projector according to customer's demand.
Fresnel lens for projector to improve the resolution, clarity, brightness, etc. of the projector screen.
In order to improve the resolution, clarity, brightness, etc. of the projector screen, we rationalize the thread pitch and tooth shape, and use an eccentric lens focusing objective lens to raise the screen and increase the range of keystone correction.
The projector can achieve a good viewing effect whether it is suspended or placed on the desktop.
