Knight Optical offer a range of Stock Ball Lenses and Half Ball Lenses, for use within Fibre Optics, Signal Coupling and Barcode Scanners. As the name suggests ball lenses are spherical lenses mostly made out of High Refractive Index Glass such as Sapphire, and LASFN-9 Glass. The reason ball lenses are most commonly used is for their ability to couple light in and out of fibres. The key feature of ball lenses is their short back focal length allowing for precision coupling where size or space is a limiting factor in the system. Ball lenses are typically used in pairs with one lens acting as a collimator for the second to focus the light back into the coupled fibre. Where a more compact solution is required a half-ball lens is typically more suitable. We hold a large inventory of Ball Lenses. •Stock sizes from 0.5 5mm to 10mm diameter. •Custom sizes available to quotation. •Half Ball lenses also available. For more information read PDF….

Knight Optical can offer Calcium Fluoride Lenses for use within the Oil and Gas Industry. We supply a range of calcium fluoride 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 in the oil and gas industry for use within detectors and spectrophotometers. For spectroscopy, calcium fluoride is superior to many other materials such as N-BK7 or fused quartz due to a lack of OH absorption peaks. Due to calcium fluoride’s low absorption and reflection and high damage threshold these lenses can often be used uncoated and are ideal for use in laser applications as well as thermal imaging systems, spectroscopy and high energy neutron detection.

Knight Optical can supply you with custom made Diamond turned aspheric lenses for use within autonomous vehicle LiDAR systems. Autonomous vehicle LiDAR systems create driverless cars. Whereby the system produce autonomous vehicles which can perform complex manoeuvers and drive in public with little or no input from a user. Spherical aberration occurs in common singlet lenses, which results in an image that appears distorted, aspheric lenses correct spherical aberration. An aspheric lens surface is designed non-spherical, which allows a single component lens to collimate or focus highly divergent rays potentially replacing a multi-lens system. This in turn provides the LiDAR system with a better signal quality, at lower costs whilst making the system more compact. Knight Optical offers diamond turned aspherics from a range of suitable NIR materials for autonomous vehicle LiDAR including N-BK7 or equivalent, sapphire, quartz, UV fused silica, amongst others.

Economic acquisition, powerful performance values and simple handling – these characteristics are combined in a robust metal construction of the air cleaner TAC 1500 S that is suitable for use on construction sites. Its Monoventic regulator enables you to steplessly adjust the air volume precisely to your actual needs, and the flexible filter system allows for the use of variable filter combinations for every construction site situation. With the TAC 1500 S you can reliably filter coarse and fine dust or spray paint mist as well as concrete dust, fine sanding or plaster dust and highly dangerous quartz dusts or asbestos fibres. The filter frame can be flexibly equipped with one or two filter elements, for example a G4 filter or an additional F7 filter, so that in combination with the HEPA filter a two- or three-stage air purification process in accordance with dust class H can be achieved.

Glass beads are a low-cost alternative for Raschig rings. They have less surface area than the rings, and therefore a reduced separation capacity, but they are perfectly adequate for many applications. Our glass spheres can also be supplied with a matt surface. Various types of glass are possible for our glass beads: Soda glass Borosilicate glass 3.3 Quartz glass On request, we can manufacture borosilicate or quartz glass beads with dimensions according to your specifications.

We manufacture reagent and centrifuge tubes in standard sizes and also with special dimensions and versions from soda glass, borosilicate glass, neutral glass, and quartz glass – optionally with or without flanged rim. All our tubes have a flame burnished rim and can be supplied with a rounded, flat or pointed conical bottom. We are able to process tubes with diameters up to 40 mm, and lengths up to about 500 mm – also thick-walled tubes. Special reagent micro tubes We are able to manufacture reagent micro tubes with rounded bottoms, i.e. with very small dimensions. For example, soda glass tubes with rounded bottom, flame burnished rim, 3 mm diameter, and a length of 20 mm. Test tubes with notch for thermal processes These special test tubes were developed to enable ventilation of the tube’s interior during a thermal process. The notch prevents complete closure and thus an over pressure.
