Knight Optical We offer Stock Polarisers used in the visible range in cameras/photography. We supply a range of Polarizer options for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Linear Polarisation can be split into P-Polarised (Light where the electric field is Parallel to the plane of incidence) and S-Polarised (Light where the electric field is Perpendicular to the plane of incidence) light, where a polariser can be used to eliminate one plane of polarisation. This is done to decrease ‘glare’ (reflections on the surface) when an image is being taken, and increase the contrast. This is used often with cameras to obtain ‘better’ image quality at the expense of an image that appears slightly darker. For more information read the PDF….

KO can offer Metallic Neutral Density Filters for use in Photographic Applications. We supply a range of Metallic Neutral Density (ND) Filters for a variety of applications – all individually QA checked and metrology tested for quality to ensure parts meet customers’ specifications. What’s more, our Metallic ND Filters are supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Our Metallic ND Filters reflect (with a metallic coating) light neutrally over a wavelength range (typically visual). They can be used to lower the intensity of light prior to the image plane. These are often used in photography, allowing photographers more flexibility with their setups to achieve desired effects. Often, an ND filter will be used in conjunction with a long exposure to prevent washed-out and overexposed images. They can also be used to add motion blur, reduce depth of field and to use a wider aperture.

Knight Optical can offer Pellin-Broca Prisms for use within Atomic Spectroscopy. We supply a range of Pellin-Broca Prisms for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers within Atomic Spectroscopy. Pellin-Broca Prisms are designed with a given material, angle and wavelength in mind to perfectly deviate a beam of the given wavelength by 90 degrees. These are often used to separate beams of differing colours and as such are ideal for use in optical atomic spectroscopy or to separate outputs of a multi-line laser. For more information read PDF…

Knight Optical can offer custom Rod Lenses for use within Optical Systems. We supply a range of custom & stock Rod lenses for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers with Optical systems. Rod Lenses are a special variant of cylindrical lenses so they focus light to a line. Rod lenses have an outside face that is polished and the ends are ground. Typical uses for rod lenses would be to generate a line image from a circular laser beam. Rod lenses can be cut at 45 degrees for use in beam steering and other similar applications.

Knight Optical can offer dichroic bandblocking filters for use in Fluorescence Microscopy. We supply a range of dichroic bandblocking filters for a range of applications. All individually QA checked and metrology tested for quality to ensure parts meet customer specification. Supplied in a range of sizes and shapes with custom coatings tailored to meet your individual applications. Knight Optical supply precision optical components to customers in fluorescence microscopy. Dichroic bandblocking filters are used to block a specific wavelength band and transmit the rest. Our Dichroic bandblocking filters are usually made for bands between 300-1200nm. Our dichroic filters are usually specced for a 0° AOI. Use at a 45° results in a CWL shift of around 35-50nm. They are used as beamsplitters in fluorescence microscopy to transmitting For more information read PDF….

Knight Optical can offer UV Fused Silica Windows for Vacuum Applications. UV Fused Silica is a relatively hard optical glass with a very low coefficient of thermal expansion. This means that it is a good choice for us in Vacuum applications, as any difference in temperature will not affect the optical performance. In addition to the above, UV FS has high transmission from UV to NIR meaning that there is little loss of image when it is used for a Vacuum Window/viewport and therefore the quality of the optical system is not compromised. All our UV Fused Silica Lenses are fully inspected on their quality in our ISO 9001 certified, state-of-the-art Metrology laboratory, using our Trioptics Optispheric, and Starrett AV300 and Zygo Verifire XPZ. This allows us to work to the highest QA standards and meet the tolerance specifications on these precision components Read PDF for more info Material::UV Grade Fused Silica Operating Wavelength::587nm Diameter Tolerance::+0 / -0.10mm Centring Tolerance::<5 arc min Focal Length Tolerance::± 0.2mm (<10mm) ±2.0% (10mm – 1000mm) Centre Thickness Tolerance::±0.2mm Surface Figure::3/ 3 (1) Surface quality::<40-20 Scratch/Dig Coating::Optional

Knight Optical offer a range of Stock Achromatic Doublet Lenses for use within Light Engines. Light engines are used for applications such as fibre optic lighting displays & in diagnostic tools like western blots & polymerase chain reaction systems. These Light Engines are typically able to produce changing colour displays. Within the light engine are a range of lenses & filters. The lenses help to homogenise and collimate the light, ensuring for a crisp high-quality beam output. Achromatic Doublets are typically used in light engine systems & correct for chromatic aberrations which exist in singlet lenses. This is when different wavelengths of light refract at different rates. The doublet lens helps to correct this by facilitating the focusing of the light to the same point. This is especially important in light engines which typically generate white light.
