Optical sensors - Import export

Germanium wafers are a semiconductor material & therefore are a smart choice for microelectronics. Due to its unique electric properties, it is widely used for sensors, solar cells and infrared optical applications. The wafers are also great for microelectronics as the space is limited and being available in 500μm or less it makes it perfect to achieve the high quality results required. It’s thermal conductivity makes it a good alternative to silicon. Our stock wafers are produced as thin as 500μm and provide exceptional surface quality. However, we can manufacture to a fully customised specification with a wafer thickness as little as 10 μm. Typical specifications of our germanium wafers are: 10mm – 150mm in diameter <500μm in thickness Doped and undoped Germanium

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

New for 2019, Knight Optical’s newly expanded collection of Moulded Optics now further meet the demands of the most complex, high-specification projects. Drawing on our 28 years’ experience and passion for producing premium-quality components, we now provide an even greater component offering within our Moulded Optics range. From Quartz Tubes and Aspheric Lenses to sought-after Germanium Windows and Fresnel Lenses, our optics are specified for a diverse variety of applications – such as magnification and light diffusion. One of the most popular uses for Moulded Optics is light sensor devices. Connected to floodlight circuits and used to detect movement within their radar, these devices are commonplace within the defence industry and for home and workplace security usage. Their operation lies within their ability to identify infrared (IR) wavelengths emitted from objects within their field of view. Read PDF for more information….
