Knight Optical offer a range of Stock Ball Lenses and Half Ball Lenses, for use within Fibre Lasers. As the name suggests ball lenses are completely 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 focus light when leaving a fibre optic, so that it can therefore be used for a laser application. 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.

At Befort, spherical precision optics pass through the hands of qualified specialists. They work with a sure instinct and stateoftheart technology. The machine processing of each surface is done on CNC grinding and polishing machines. We produce spherical precision lenses from optical glass, quartz glass and radiationresistant materials with diameters from 3 mm to 130 mm and a curvature radius from 1.18 mm to plane. We make individual lens elements, achromatic systems, concave mirrors, cylinder lenses and other precisely fitting glass geometries to suit your specific application.

The GREEN CLEAN – Silky Wipe cleaning cloth is a silk derivative cloth that is effective for safely cleaning TFT LCD LED & plasma panel TV’s, monitors, mobile display, tablet pc`s and other electronic devices. These special cloth is also effective for cleaning lenses, optics & glasses. Silky Wipe is made from a particularly flat, tightly spun silk derivative and contains no chemical binding materials or bleach. To be used dry or with liquid. The quality of the cloth is therefore very soft, yet has the slow absorption qualities necessary to make this particular cleaning process so effective. SILKY WIPE washable at 30° extremely good polishing quality individual sealed 25 x 25 cm / 9,84 x 9,84 inch no microfibre GREEN CLEAN – “Silky Wipe” for: Lenses – Optics – Touch Phones – GPS / navigation device – Photo Frames – LCD/LED/Plasma TV´s – Tablet PC´s

Knight Optical can offer UV Fused Silica Lenses for Solid State Laser applications. UV FS is a prime choice for lenses in use with Solid State Lasers due to its consistently high transmission in the UV/VIS/NIR regions. This means that it can be used with a range of different laser types, such as Titanium-doped sapphire (tuneable to 660-1080nm) or Alexandrite (tuneable to 700-820nm) with very little change in performance. UV FS is comparable to N-BK7 or other similar optical glasses in its performance, having a very similar average transmission over the VIS range up to approximately 2000nm and a slightly lower refractive index. The Abbe constants of UV FS are also very similar to that of N-BK7, although slightly higher. Read PDF for full specification

Knight Optical can offer you Stock and Custom Fresnel Lenses, for use within Retinal Imaging in a range of materials such as PMMA Acrylic and Borosilicate. Our Fresnel Lenses consist of a flat surface with interspace concentric steps whereby each step corresponds to the surface of a conventional lenses. PMMA Acrylic is a preferred material type used for retinal imaging Fresnel lenses. The Fresnel lenses are used as part of a system where its multi-focal length provide a multiple in and out of focus image that provide a magnified image of the human eye itself.

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.
