S-FCL Series ALR (Ambient Light Rejection) Fresnel Screen for Standard/Long Throw Projectors
Changhong S-FCL series ALR screen is made of Fresnel optical materials.
Optimised for standard/long throw (throw ratioThrow Ratio The throw ratio of a projector refers to the ratio of the distance between the projector and the screen to the width of the projected image. This ratio determines the size of the image based on the projector's distance from the screen, making it a crucial factor in choosing the right projector for a specific space. To calculate the distance between the projector and its screen using the throw ratio, one can use the following formula: Distance = Throw Ratio x Width of the Image For instance, if a projector has a throw ratio of 1.5:1 and the desired width of the image is 6 feet, the distance from the projector to the screen would be 1.5 x 6 = 9 feet. Understanding the throw ratio and its calculation is essential for setting up a projector to achieve the desired image size and optimal viewing experience based on the available space. between 0.6-1.8:1) projectors, with its advanced, multi-layer optical material, S-FCL screens can efficiently reject 85% of the ambient light that come from the top and both sides of the screen to deliver vivid images under ambient light conditions.
More than just making the image brighter, S-FCL series dramatically (up to 30 times) enhance the image contrast and colour saturation.
Brighter Image
The S-FCL Fresnel lens focuses the light from the projector and sends it straight forward towards the viewers. As a result, it is able to offer 2.0 screen gain which means the perceived projection image brightness is 2.0 times higher than what’s perceived from the projection image on the white screen.
The 2.0 screen gain makes S-FCL ideal for projector with low native brightness such as the popular LED projectors.
Magnetic Rollable Screen
Fresnel screens normally delivered in a one piece form which make the transportation and installation difficult.
S-FCL screen’s unique rollable design makes it is easier to transport,
The back of the screen is a magnetic layer. To install the screen, simply place the supplied magnetic self adhesive sticker on the wall, then attached the screen on the adhesive sticker pads, the screen will get snapped on without hassle, without drilling.
85% Ambient Light Rejection Rate
The core element in S-FCL screens is the Fresnel lens. The Fresnel is made up from thousands of concentric lenses – each with its own unique profile. Barely visible to the naked eye, these lenses form a circular pattern from the screen centre and outwards – like ripples in a pond.
With S-FCL screen, only light from the projector will be focused and ambient lights from both sides and top of the screen will be rejected.
The S-FCL screen can efficiently reject over 85% of the ambient light which makes the image vivid and bright under ambient light.
Hot Spot Avoided
Producing uniform images is essential for any projection system. Even small differences from corner to centre and between neighbouring screens can irritate the eye,
Normal white matt diffusion screens can suffer from “hot spot” problem because they are unable to redirect the light. Because the projector is always angled away from the viewer in the corners, a “hot spot” can be observed in the centre of the screen.
S-FCL’s Fresnel screen focus the light and redirect it back to the viewer. Because the light’s redirection is controlled, you can expect a well uniformed image without “hot spot”.
Ultra-Slim
The magnetic and rollable design save the S-FCL screen from bulky frame structure.
The screen is super slime with the a thickness of just 5mm.
