Our Linear Polarisers linearly polarise unpolarised light and can block light that is polarised in the opposite direction. Linear Polarisers are often used in the production of LCD monitor and TVs. 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...

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….

The VQuad can be mast mounted, radome protected, and elevated up to seven meters or mounted permanently onto any platform. VQuad is based on the field proven and award winning QuadTac, however, there is no requirement for the dipole arms to close which allows for larger dipole elements to be used. This provides increased sensitivity at the lower operating frequencies.

The MicroQuad antenna is typically used in conjunction with the QuadTac where it provides a base for the QuadTac. It can also be operated in isolation if only HF spectrum monitoring is required. Features: •Low visual signature •Rapidly deployable •Lightweight, compact folding design •Integrated GPS antenna

The Quadrant antenna provides detection of frequencies at the lower end of the HF spectrum (up to 32MHz) and is the largest and most accurate in the RESOLVE antenna range. It is ideal for Semi-Static configurations where it can be quickly deployed. When collapsed the Quadrant antenna fits into a custom carry bag and is easily carried by two men. Features: •Detects frequencies at the lower end of the HF spectrum. •Greatest accuracy of all the antennas in the range. •Compact folding design which can be deployed in 90 seconds

The QuadTac antennas provide 2-channel intercept and Direction Finding capability for a RESOLVE system. Specifically designed for On-the-March operations, the antenna can operate with the array elements extended for maximum sensitivity, or closed to reduce the visual signature. Features: •Low visual signature – QuadTac Mini has reduced height; the array elements in the QuadTac can be closed and still maintain intercept and DF capability •Rapidly deployable – lightweight, compact folding design (QuadTac) •Bearing Reference – built-in electronic compass provides absolute or relative Lines of Bearing •Flexible – manpack, tripod or vehicle mounted •Accurate – Built-in GPS provides accurate antenna location and system timing •Modular – Integrates with MicroQuad antenna subsystem
