Knight Optical can offer Gas Cells for use within the Chemical Analysis. We supply a range of Gas Cells 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 the chemical analysis industry. Gas cells are used in spectroscopy for identification of the contents of gases. The path length and window material are chosen for analysis of different concentrations and types of gas. Depending on the types of gases being analysed, the windows in a gas cell can be made from NaCl, KBr, CaF2, BaF2, or ZnSe and will be chosen depending on bandwidth, to meet the customer’s application. All our Gas Cells are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory

Our ranges of light guides are available in a variety of materials Currently we offer BK7 or equivalent, Sapphire or equivalent and UV Fused Silica light guides, in an assortment of diameters and thicknesses. Light guides serve as the key element in cosmetic laser, or intense pulsed light (IPL) applications. IPL is commonly used for the removal of unwanted hair, as well as a range of other cosmetic applications. IPL applications make use of a variety of wavebands to target different chromophores. For this reason, our custom light guides are available in a choice of materials to suit your waveband requirement. Knight Optical’s custom BK7 or equiv light guides offer high internal reflection to minimize the loss of transmitted light. BK7 or equiv can offer over 90% transmission between 330 and 2000nm, which makes this material an excellent choice for IPL applications used to treat pigmentation Continue to read thePDF

As well as Knight Optical’s Low GDD Ultrafast Laser Mirrors, we can also provide broadband and wide-angle alternatives to cover more of a range of applications. Our Wide-Angle Laser Mirrors optimised for the fundamental and second harmonic (SHG) emissions of Ytterbium (Yb) doped lasers including diode-pumped solid-state (DPSS) and fiber lasers, and therefore have a design wavelength of either 515nm or 1030nm. They exhibit > 99.9% reflection when used between 0 to 45°. The Broadband Laser Mirrors work from 700-900nm ideal for applications using a Ti:Sapphire laser, again demonstrating > 99.9% reflection within this wavelength range. Their key features include: •Ion beam sputtered (IBS) coating which is compact and durable. •Reflection > 99.9% within their design wavelength range. •Broadband laser mirrors work at 45° •Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening •High laser induced damage threshold (LIDT) •Precision flatness and surface quality to

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….
