The bright image produced by Intenscreen begins with Beattie's precision fresnel lens design. Made from high quality optical grade acrylic, Beattie fresnel lenses are optically engineered to concentrate and redirect light (and the image) to the exact position of the eye.
Traditional ground glass-type focusing screens simply act as a surface for viewing the image and don't effectively utilize all of the available light, resulting in a dim image with little contrast.
In addition, Intenscreen focusing screens go through a a special chemical coating and curing process adding even more brightness. This start-to-finish manufacturing process is so innovative that it has been patented!
