In projection systems, Fresnel lenses are used to collimate and focus light.
The Fresnel lens collimates the light beam returned from the light source into a parallel beam, significantly enhancing the brightness around the edges of the panel.
The spot effect has been eliminated, thereby improving the overall uniformity of display brightness.
Advantages of using Fresnel lenses in projection systems: by focusing or collimating the light, they increase the brightness of the projected image.
If the collimating lens is removed, significant light loss will occur as the beam passes through the panel, resulting in a pronounced hot-spot effect and increased brightness across the display screen.
Similarly, on the other side of the LCD screen, we must also collimate the light from the panel and direct it into the projection lens.
Our company can customize projection lenses of various sizes, shapes, and focal lengths to meet customer requirements.
Fresnel lenses for projectors are used to enhance image clarity, brightness, and other performance metrics.
Optimize the thread pitch and tooth profile, and to elevate the image and expand the keystone correction range, adopt an eccentric design for one of the lens condenser objectives.
Ensures optimal viewing performance whether the projector is ceiling-mounted or placed on a desk.

In projection systems, Fresnel lenses are used to collimate and focus light beams. Fresnel lenses convert the divergent light emitted by the source into a parallel beam, significantly enhancing the brightness around the edges of the display panel and eliminating the hot-spot effect, thereby improving the overall uniformity of screen brightness.
