Homogenizing Rods for Fluorescence Imaging

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. Read PDF for more information

Knight Optical offer a range of Stock BK7 Windows, for use within Wind Monitoring LiDAR Systems. These LiDAR systems are used in monitoring wind speeds and wind direction. The data accumulated can be used to generate a Digital Terrain Model or a Digital Elevation Model which are 3D representations of terrain. BK7 is one of the most widely used optical glasses available for use in the range from visible up to the near infrared. Making it ideal as a protective optical window for Wind LiDAR systems which operate at 1500-1560nm. The BK7 can offer an uncoated average transmission of 92% between 300nm and 2000nm.

Knight Optical offer a range of Stock N-BK7 Precision Grade Windows, for use with Thermal Imagining Cameras. Infrared radiation is characterised by the wavelengths ranging from 750nm to 1000µm. Although typically used for the visible range, N-BK7 does have transmission within the near infrared spectrum also. Where IR materials such as Germanium are limited to a small band in the IR spectrum, N-BK7 works well throughout the entire visible and into the NIR, making it a perfect material for a protective window for using within a Thermal Imaging Camera. A low cost material, it is perfect substrate for your protective window. We can supply both stock and custom N-BK7 windows to protect your thermal imaging application. The high optical quality and uniform transmission of N-BK7 as well as low absorption in the entire visible wavelength range is a key feature for this application. For more information read PDF

Knight Optical provide a wide range of optical components present in a spectrometers, specifically mirrors and prisms with a UV Aluminium coating to enable the detection of UV wavelengths from 180nm. UV wavelengths can be hard to detect without the use of this coating and can make results inaccurate. Knight Optical UV Aluminium coating allows wavelengths between 180-650nm to reflection at an average of of 85% which is not achieved with Enhanced Aluminium which cuts on at 400nm and primarily for the visible region and above. The coating can be applied to Prisms and Mirrors, either from stock or custom. It is also worth noting that the coating has a protective layer which improves resistance to scratching and improves durability making it easier to clean. Read PDF for more details
