Laser engraving is often used to personalise products, such as beautiful wine boxes with a corporate logo or a personalised glass with decorative lettering. With such a vast range of materials suitable for engraving, the applications are virtually endless. Frequently used materials include wood, metal, glass and plexiglass. Our clients customise products such as wine glasses, beer mugs, pens, mirrors and wooden appetiser planks with our laser engraving machine. The laser machine software can read different file formats, such as .ai and .dxf. You can therefore always continue to work with your favourite graphic design software, such as Adobe Illustrator and AutoCAD. The laser head moves at high speed, and the beam rapidly switches on and off. This makes the machine a kind of printer that burns the design onto the material. The laser machine is controlled by software which supports vector files.

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..

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

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..

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.

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.

Optical Coherence Tomography otherwise known as OCT is an advanced technology used specifically within retinal imaging and analysis. This non-invasive technology was designed to provide highly detailed images of the retina as well as the optic nerve. It uses light waves to take cross-section images of your retina, using OCT it is possible to see each of the retina’s distinctive layers. Within OCT’s, a light source with a broad optical bandwidth is used for illumination and is split by a Non-Polarising Beam-Splitter into 2 paths referred to as the reference and sample arms. The light from both the reference and sample arms are reflected back and combined at the detector. An interference effect is seen at the detector in the reference and sample arm only if the time travelled by the light is nearly equal. Read PDF for more info

Optical flats are single precision flat surfaces. They are used as reference surfaces to compare flatness of a substrate where flatness is unknown. When a high quality optical flat is placed on top of a polished substrate and used in conjunction with a monochromatic light source light bands are formed. The light bands that are present are known as interference fringes and their shape represents how flat the part being tested measures. Dependent on how many rings are formed or how straight the presented lines are is an indication of how flat the tested part is. Optical flats are used for testing gauge blocks. Optical flats are also used in interferometers and high quality flat optical mirror and window sub-straights for laser applications. This range of quartz optical flats are single-sided. Quartz has low thermal expansion properties and is very durable and cost effective solution over UV grade fused silica. Read PDFs for more information

Their key features include: •Ion beam sputtered (IBS) coating which is compact and durable. •Reflection > 99.9% within their wavelength range of either 500-530nm or 1010-1050nm. •Available as 0° and 45° angle of incidence •Exhibit minimal group delay dispersion (GDD) to prevent pulse broadening •High laser induced damage threshold (LIDT) •Precision flatness and surface quality to minimise laser scattering All of the above are important criteria for mirrors used to form a laser resonator, making these laser mirrors ideal.

Knight Optical We can offer Custom Moulded Aspheric Lenses for use with Laser Diode Collimators. Aspheric lens surfaces are used to correct spherical aberration (where the converging light from a lens does not have a common focal point, resulting in a distorted image) in lasers and imaging. Traditional spherical lenses cannot collimate light effectively because even small angles of incidence can produce spherical aberrations. This can mean that several components may be required to get the desired result. The non-spherical surface of an aspheric lens allows a single component to effectively focus or collimate even highly divergent emissions, potentially replacing a multi-lens system with a single aspheric lens. Therefore Aspheric Lenses that are moulded are ideal for use within laser diode-to-fibre coupling applications. For more information read the PDF..
