The liquid crystals act like a wave-plate, rotating the polarisation axis allowing them to control the amount of light from each pixel. They are used in a similar way for a photographer to prevent surface reflections from water. Our polariser sheets allow different levels of total light from a randomly Read PDF for more information...

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,

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

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….
