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..

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

Knight Optical can offer you stock and custom lambda/10 mirrors for use in government testing for aerospace, in a range of materials such as BK7 or equivalent, Zerodur, Quartz, UV Fused Silica and many more. Mirrors are made from low expansion glass for optimum stability to maintain the lambda/10 flatness. The mirrors help produce high quality images and can be coated with a variety of coatings to ensure that the perfect quality image in the wavelength you require is achieved: Enhanced aluminium 94%R for visible applications. 99.9% dielectric for laser use in visible applications. UV aluminium for UV applications down to 180nm. 98.5% dielectric for laser use in the NIR applications. Ion plated silver for NIR-2000nm applications. Protected gold for 750nm to far infra-red applications λ/10 mirrors are used in the aerospace environment due to the vibration, temperatures & pressure through which they are exposed.

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.
