Many materials cannot be measured tactilely, therefore non-contact thickness measurements become necessary. Especially e.g. with glowing materials, or wet processes, a continuous tactile measurement is nearly impossible. Furthermore, web speeds in plant engineering and production have increased, requiring a corresponding fast sampling rate of the measuring systems. In addition, high measuring widths are often required. Why is contact free measurement technology so perfect for this application? Can be used in any web width, Scalable measurement thicknesses from a few millimetres to several meters, Thickness and coating thickness can be measured for different materials, Vibrations of the web materials, can be compensated, Turnkey solution for mechanical engineering, Non-contact and non-destructive measurement method, Large distances to the measured object are possible, Measurement of free forms,

Particular Challenges: The seal surfaces in this case are made of very glossy metal, with the drawback of emitted reflections. This effect during an optical measurement must be eliminated. Furthermore, it is absolutely necessary to guide the laser scanner on a linear path over the surface, since fluctuations of distance may falsify the measurement result. QuellTech Solution: The Quelltech model Q5 disposes of an adequate resolution in X and Z direction and proves to be able to verify the planarity tolerances and to measure the size of defects. Meanwhile a precise rotary axle, used as guiding element, moves the scanner over the surface to be evaluated. Interfering artefacts caused by the glossy finish are suppressed by particular algorithms integrated within the software. As an encoder value is permanently supplied by the rotary axle, the position of each scanner profile within the point cloud can accurately be determined.

Knight Optical offer a range of Stock Polarisers that can be used in the study of insect vision. Insects exhibit sensitivity to linear polarised light. Insects polarise light in their vision for a number of reasons such as reducing glare and to increase contrast. This is also widespread practice in most modern cameras to help ensure the resulting image is as sharp as possible. Additionally, recently the study of insect vision has allowed researchers to modify camera systems incorporated in aerial drones to help fly independently through dense forests by assessing light intensity to avoid other objects. Knight Optical works with many leading research institutions in the field of insect vision. Knight Optical also keep stock a UV and NIR range of sheet polarisers. In particular our HNP’B replacement UV polariser which has excellent performance from 250-750nm is utilised heavily within the research of arthropod vision. Read PDF for more information

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

Plastic materials may crack under the prolonged exposure to a UV light source… But not Knight Optical’s Dichroic Hot Mirrors! Knight Optical can supply you with high quality and cost effective Dichroic Hot Mirrors for use in optical systems where unwanted UV or IR light negatively impacts on the system quality. This includes UV and IR Sensitive Systems, medical illumination and display fibre optics. Prolonged exposure to UV light can cause degradation in plastic materials resulting in cracking and, eventually, mechanical failure. Exposure to IR can cause undesired thermal energy and heat into the system that can damage delicate components. Dichroic hot mirrors solve this issue by reflecting UV and IR light away from the component, meaning cost We hold a massive inventory of Bandpass, Long pass, Short pass, Band-blocking and Colour-correction filters.

Knight Optical offer a range of Stock N-BK7 Dome Windows, for use with Underwater Lighting. A dome is an optical window composed of two parallel curved surfaces. Domes are commonly used in defence applications and often in extreme environments such as Submersible ROV’s. The shape of the window creates a naturally strong shape that gets tougher under pressure. Using a curved dome optical surface allows for an increased beam angle, therefore allowing a greater area to be lit from one light source. For visible applications, N-BK7 with its high optical quality and uniform transmission and low absorption in the visible spectrum makes it an ideal material for underwater lighting. A tough and cost effective solution which allows for good transmission of the light source in the underwater environment will both protect the light source as well as transmitting from 300nm up to 2µm.

Hydrophobic means to repel water. Applying a hydrophobic coating to a surface can help the surface repel dirt and residue for easier cleaning. These types of coatings also have an oleophobic property, meaning that oil and grease is also repelled. Knight Optical provide Hydrophobic Coatings to wide range of protective windows made from materials such as BK7 or equivalent, UV Fused Silica or Borosilicate. Benefits for hydrophobic are that is: Optically Clear Easy-to-Clean Fingerprint and Smudge resistant The properties of the optical component itself remain unaltered meaning it does to hinder its current application or require a redesign. This coating would be a custom item and can be applied to most of our stock optical components.

Within medicine the use of polarised light was first introduced back in the70’s; since then it has come leaps and bounds. How it has been used to help with imaging skin pathologies, when the skin is illuminated by linearly polarised light it causes backscattering of the superficial layers of the skin where cancer often arises. This superficial backscattered light can be distinguished from the diffused reflected light when using a detector. Polarised Beam-Splitter Cubes, Sheet Linear Polarisers, and Sheet Circular Polarisers are often used within detection devices for this type of skin pathology imaging. Knight Optical hold a large inventory of Polarisers for use within Skin Cancer Detection devices. •We stock large sheets up to 1270x480mm in some cases; we can cut these into special shapes at short notice. •Mounting options are also available. •Special Glass laminating to CAB polarisers •Special AR coatings.

The laser mirrors can be custom made to include the following range: 1 YAG laser mirrors (High power grade) 2 Excimer laser mirrors (High power grade) 3 Argon-ion laser mirrors (High power grade) 4 Diode & broadband (Ti:Sapphire) These mirrors are made from vacuum depositing thin films of material that have differing refractive indices & thickness onto suitable substrates. Typical custom laser mirror substrates are calcium fluoride, germanium, sapphire, fused silica and Zinc Selenide which produce a high efficiency reflecting surface at the laser wavelength. The coatings are assembled assuming that the mirror will be working in the plane of incidence. This is essential as any off-axis angles will push the pass band toward the shorter waveband that could be beyond the pass band for one or both polarizations (s and p). If off-axis reflections are needed, such as at 90°, then this coating needs to be applied for an Angle of Incidence (AOI) of 45°. READ PDF FOR MORE INFO ..
