Ball Lenses are widely used for focusing & coupling light into & out of fibres. With the high refractive index of Sapphire (Al2O3) material, it yields a low spherical aberration that can be used in the range of UV from 200nm up to 5µm, and with it being one of the hardest materials they are resistant to damage. 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. Typically used in pairs, where one lens acts as collimator for the second to focus the light back into the coupled fibre. Ball Lenses are manufactured from a single substrate of glad and therefore, depending on the geometry of the input source, can focus or collimate light. Half Ball Lenses can also be used as an interchange with a full ball lens for more compact designs. Read the PDF for more information...

Due to high intensity light from the laser, mirrors used with a laser application require a high damage threshold, and high reflectivity. Knight Optical can help! Laser mirrors are used to reflect or redirect the laser. This manipulation of the beam means it is great for laser applications where there is limited space, as the beam can be steered multiple times. We manufacture mirrors used in the UV/VIS/NIR and infrared. We provide a number of mirrors from stock with coatings at infrared wavelengths such as: Dielectric (98% NIR) Protected Silver (96% VIS/NIR) Protected Gold (97%@750-FAR IR) These are available to purchase from stock in a wide ranges of sizes from 6.3 mm in diameter to a 300mm x 300mm square and various different thicknesses. They are also available with varying flatness specifications with λ/10 also available for immediate shipment and for you to achieve the highest performance. Read PDF for full specification..

How optical mirrors are used in conjunction with these devices is that, a mirrored surface can be measured with a laser tracker; which will help determine the distance between the laser distance Read PDF for full information..

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.

Intense Pulsed Light Systems use not only use filters, that are used to filter out the UV wavelength range; and transmit between 400-1200nm for use within cosmetic lasers that are designed to remove unwanted hair, vascular treatment and even acne treatment. But they also use Homogenizing Rods to help evenly distribute light. The Light source will enter a light pipe at a variety of incident angles, which is designed to utilise its total internal reflection to channel the light from the entrance of the light pipe to the exit. The material’s refractive index is the only factor which affects the light pipes critical angle; this defines the angle of acceptance which the total internal reflection will occur at. All our Homogenizing Rods are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptic’s PrismMaster, and Starrett AV300 Video Imaging System..

Knight Optical can offer Lithium Fluoride Windows for use within UV Applications. We supply a range of lithium fluoride windows for a range of applications. All individually QA checked &metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes & shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers using UV optics such as UV lasers. UV lasers are beneficial in some applications as opposed to longer wavelengths such as infrared or visible light as they do not heat the areas around the target. This allows the laser the cut materials by breaking atomic bonds, rather than melting the material. Due to the large band gap for Lithium fluoride, it’s crystals are more transmittive to short wavelength UV radiation than any other material and are ideal for use in X-Ray monochromators, as for use in VUV, UV, Vis and IR spectrums.

The laser mirrors can be custom made to include the following range: 1 YAG laser mirrors (High power grade) 2 Excimer laser mirrors (High power grade) 3 Argon-ion laser mirrors (High power grade) 4 Diode & broadband (Ti:Sapphire) These mirrors are made from vacuum depositing thin films of material that have differing refractive indices & thickness onto suitable substrates. Typical custom laser mirror substrates are calcium fluoride, germanium, sapphire, fused silica and Zinc Selenide which produce a high efficiency reflecting surface at the laser wavelength. The coatings are assembled assuming that the mirror will be working in the plane of incidence. This is essential as any off-axis angles will push the pass band toward the shorter waveband that could be beyond the pass band for one or both polarizations (s and p). If off-axis reflections are needed, such as at 90°, then this coating needs to be applied for an Angle of Incidence (AOI) of 45°. READ PDF FOR MORE INFO ..
