The ALS-2 Ambient Light Sensor is designed to measure background luminance as part of a Runway Visual Range (RVR) system. Mounted alongside the runway the ambient light sensor is often deployed with a visibility meter to provide the data necessary for calculation of RVR. Designed to comply with specifications and guidelines produced by the International Civil Aviation Organisation (ICAO), World Meteorological Organisation (WMO) and the Federal Aviation Administration in the USA (FAA), the ALS-2 meets all the requirements for use in typical RVR systems. The ability to connect the sensor directly to a Biral visibility or present weather sensor and have the background luminance data incorporated into the visibility sensors data string simplifies system design and construction.

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….

Knight Optical can offer Circular Sheet Polariser for use within Photographic Applications. We supply a range of Circular Sheet Polariser for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers within Photographic Applications. Our Circular Polarisers consist of a quarter wave plate cemented to a linear polariser. While a linear polariser may be used to reduce glare during photography (such as reflection from the surface of a body of water), autofocus systems struggle to correctly focus on linearly polarised light. With the addition of the quarter wave plate, this has little impact on the intensity of incident light to the sensor, but it makes autofocussing much easier. For more information read PDF…

The VPF-710 Visibility sensor provides high quality visibility measurement in a compact and highly robust package. The open design of the sensor head allows the free passage of air ensuring the visibility measurement is as accurate as possible in all conditions. Other features of the design ensure the correct response to all precipitation types as well as smoke and dust. The VPF-710 is highly resistant to disturbance from nearby light sources such as aviation obstacle warning lights, both constant and flashing. Even the latest generation of IR obstacle lights are not a problem. The sensor is well suited to use in aviation applications due to the measurement accuracy, overall reliability and longevity. Full compliance with the visibility measurement requirements of the International Civil Aviation Organisation Runway Visual Range specification and easy integration of the Biral ALS-2 ambient light sensor makes VPF-710 particularly suited for use in Runway Visual Range (RVR) application

Our TM1+7 SBC is makes a low cost, readily available, long life smart phone platform available for you to design your product around. We have designed, tested and approved the platform to make integration into your product as easy and risk free as possible.
