Beamsplitters for Food Sorting System

Photonics MarketplaceOptical 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 beamsplitters are one of the optical components used. Within the camera used in the system a beamsplitter 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.

Polarizing beamsplitter cubes are often used within optical sorting systems; how a polarizing beamsplitter cube works by allowing P-polarized light to pass undeviated through the cube while S-polarized light is reflected at 90°. The quality of the cube is typically defined by the extent and accurate beam deviation of the transmitted and reflected polarized light and by the extinction ratio of the cube. Like standard non-polarizing cubes, the outside faces are usually AR coated over the operating wavelength to reduce losses due to reflection. Knight Optical can offer you custom made polarizing beamsplitter cubes to meet your requirements.More products
