Ball Lenses & Half Ball Lenses for Fibre Optics

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

This month, Knight Optical is excited to unveil a brand-new range of Fluorescence Filter Sets. As its first product launch of the year, the announcement comes as welcome news to those working on fluorescence imaging applications, who demand premium-quality, ultra-precision Filter Sets for high-efficiency transmission. The launch follows the business’ 30th anniversary, which the global optics supplier celebrated last year, and demonstrates its dedication in continually evolving the growth of its already-comprehensive portfolio of cutting-edge, custom-made, and stock optical components. Here, the trusted brand discusses its new product offering and runs through the indispensable technicalities behind the sets.Filters and Sets to Meet Every Application’s Needs As a set of optics that are typically used for fluorescence applications within fields such as biology, materials science, chemistry, medical diagnostics, and mineralogy; for example,

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

Knight Optical can offer you Stock and Custom Colour Glass Filters, for use within Inline Cameras in a range of materials of brands such as Schott, Kopp and CDGM. Depending on the achievable wavelength and desired affect you need for the Inline Camera we can find a suitable material for your application. Colour Glass Filters are good for selecting a particular wavelength to be absorbed so that the high out of band blocking in achieved. With regards to the use in Inline Cameras, Colour Glass Short pass Filters are more desirable as they cut out the IR wavelengths mean the imaging is not saturated with the IR giving the image better clarity. Colour Glass Filters are polished sheets of special glass that have been cast with a dye. Colour Glass Filters generally are relatively cheap and very stable. The disadvantage with them is that they are only available in a relatively small number of variants, and so can be restrictive in shortwave selection. Read PDF for more Information….
