Knight Optical can offer custom Rod Lenses for use within Optical Systems. We supply a range of custom & stock Rod lenses 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 with Optical systems. Rod Lenses are a special variant of cylindrical lenses so they focus light to a line. Rod lenses have an outside face that is polished and the ends are ground. Typical uses for rod lenses would be to generate a line image from a circular laser beam. Rod lenses can be cut at 45 degrees for use in beam steering and other similar applications.

Knight Optical offer a range of Stock Polarisers that can be used in the study of insect vision. Insects exhibit sensitivity to linear polarised light. Insects polarise light in their vision for a number of reasons such as reducing glare and to increase contrast. This is also widespread practice in most modern cameras to help ensure the resulting image is as sharp as possible. Additionally, recently the study of insect vision has allowed researchers to modify camera systems incorporated in aerial drones to help fly independently through dense forests by assessing light intensity to avoid other objects. Knight Optical works with many leading research institutions in the field of insect vision. Knight Optical also keep stock a UV and NIR range of sheet polarisers. In particular our HNP’B replacement UV polariser which has excellent performance from 250-750nm is utilised heavily within the research of arthropod vision.

Quartz optical surfaces flat is tested on our Zygo Verifire XPZ interferometer - Optical flats are single precision flat surfaces. They are used as reference surfaces to compare flatness of a substrate where flatness is unknown. When a high quality optical flat is placed on top of a polished substrate and used in conjunction with a monochromatic light source light bands are formed. The light bands that are present are known as interference fringes and their shape represents how flat the part being tested measures. Dependent on how many rings are formed or how straight the presented lines are is an indication of how flat the tested part is. Optical flats are used for testing gauge blocks. Optical flats are also used in interferometers and high quality flat optical mirror and window sub-straights for laser applications. This range of quartz optical flats are single-sided. Quartz has low thermal expansion properties and is very durable and cost effective solution over UV grade fused silica.
