Optical Sorting Systems are a widely utilized technology used within the food industry; most particularly used in processing harvested foods such as fruits and vegetables, most notably potatoes, and nuts. Optical sorting was designed to help improve product quality, maximize throughput and increase yields. Within an optical sorting system there are four main components, the feed system, the optical system, the image processing software and last the separation system. The optical system utilizes lights and sensors housed above and below the flow of the products being inspected. It works by using a combination of light and sensors to illuminate objects; and to do this Beam-Splitters are one of the optical components used. Within the camera used in the system a Beam-Splitter cube is used to divide the light source coming from a single lens, into different channels; and each channel is filtered to a specific spectral region Read PDF for more data

Within medicine the use of polarised light was first introduced back in the70’s; since then it has come leaps and bounds. How it has been used to help with imaging skin pathologies, when the skin is illuminated by linearly polarised light it causes backscattering of the superficial layers of the skin where cancer often arises. This superficial backscattered light can be distinguished from the diffused reflected light when using a detector. Polarised Beam-Splitter Cubes, Sheet Linear Polarisers, and Sheet Circular Polarisers are often used within detection devices for this type of skin pathology imaging. Knight Optical hold a large inventory of Polarisers for use within Skin Cancer Detection devices. •We stock large sheets up to 1270x480mm in some cases; we can cut these into special shapes at short notice. •Mounting options are also available. •Special Glass laminating to CAB polarisers •Special AR coatings.
