Precision Grade Aspheric Lenses

Knight Optical can offer Cube Beamsplitters for use within the Scientific Industry. We supply a range of Cube Beamsplitters 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 in the scientific industry for use as components within spectrophotometers and interferometer. For interferometry, beamsplitters are used to separate light into two beams to compare a reference against a sample. Cube beamsplitters offer some advantages over plate beamsplitters in that they don’t suffer from ghost images and are easier to mount. For more information read PDF…

We supply a range of Visible 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 Consumer Electronics. Our Linear Polarisers linearly polarise unpolarised light and can block light that is polarised in the opposite direction. Linear Polarisers are often used in the production of LCD monitor and TVs. The liquid crystals act like a wave-plate, rotating the polarisation axis allowing them to control the amount of light from each pixel. They are used in a similar way for a photographer to prevent surface reflections from water. Our polariser sheets allow different levels of total light from a randomly Read PDF for more information...

We supply a range of Wedge Prisms 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 Forestry. Wedge Prisms are used in a similar manner to an angle gauge, when plotting the basal area of a group of trees. Wedge prisms are also used in beam steering. All our Wedge Prism are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Starrett AV300 Video Imaging System and our Trioptics PrismMaster. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components. Read PDF for more...

Knight Optical can offer transmit and receive windows and mirrors for LIDAR systems using visible, NIR (0.9 to 1.5µm) and Mid-Waveband Infra-Red (MWIR, 3 to 5µm) light. Since the 1960s, scientists have used LIDAR (light detection and ranging) to study the atmosphere. Short pulses of laser light are used to detect particles or gases in the atmosphere, like a radar bounces radio waves off rain drops in clouds. A telescope collects and measures reflected laser radiation, like a radar dish collects the radar signal, leading to a profile of the atmosphere's structure along the path of the laser beam. Researchers can then determine the location, distribution, and nature of atmospheric particles and molecular species using an advanced LIDAR method called the Differential Absorption Lidar (DIAL) technique.
