Low Distortion Fiber Optic Channel Plates
Low Distortion Fiber Optic Channel Plates

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.
