Fibre Optic Channel Plates (FOCP) are widely used as optical devices to replace optical lenses because they require no focusing distance making them an ideal component when creating a compact optical device. Comprised of a bundle of micron-sized optical fibres - FOCP are used as a lens to transmit light or an image with extremely high efficiency and low distortion. In each single fibre of a FOCP the light is transmitted by total internal reflection that occurs at the boundary between the core glass and the cladding glass due to the difference in their refractive index.

A key component to prevent the image sensor from deteriorating due to exposure to X-rays

FOCPs are widely used to couple light to solid state imaging devices such as CMOS and CCD image sensors. Used as the light receiving surface of an X-ray imaging device, the FOCP processed by Optical Surfaces Ltd is a key component preventing the image sensor in the camera from deteriorating due to exposure to X-rays.
