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 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.

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..
