Four QuellTech Q6 3D- laser scanners are installed, mutually displaced by an angle of 90°. In this configuration, they are able to monitor the complete surface of the cable running through. It is important that the test does not lower the production speed, therefore very high sampling rates are required, supported by convenient data processing. The measured position of a defect is recorded in cable direction.

The new QuellTech Q5 Laser Scanner Series combines the advantages of small form factors with both high resolution and scan rate. The sensor disposes of different set-up possibilities with respect to the analysis algorithm. Measurement results are delivered via Ethernet, calibrated in the X / Z plane. Special adjustable algorithms can be selected, extremely useful particularly also for optically most demanding surfaces. Time-consuming calibration tasks for the user are no more required, as the calibration routine runs on board. High Scan Rate with up to 14,000 Profiles per Second Due to an appropriate limitation of the image range (AOI) in X and Z direction, the scan rate could considerably be increased. High resolution and detection frequency with up to 14.000 profiles and 28 Mio. points per second •X measuring range from 10 to 1022 mm •Z measuring range (height) from 5 to 878 mm •Laser wave length blue 405/450nm, red 650nm

Colorimeters measure colour in a substance, for example in water. It defines the measurement of the colour to enable its identification, using the lightwave spectrum. Colorimeters are a form of a spectrophotometer. The use of mirrors in the system, redirect the light beam from the light source to the sample and back to the sensor to enable a reading. Knight Optical provide high quality coated front surface mirrors of varying reflection averages from stock and to custom specifications. Knight Optical provide several metallic coatings such as: •UV Enhanced Aluminium •Enhanced Aluminium •Protected Silver •Protected Gold •Visible Dielectric •NIR Dielectric These are all available as custom coatings depending on your requirements for your colorimeter.

Optical flats are single precision flat surfaces. They are used as reference surfaces to compare flatness of a substrate where flatness is unknown. When a high quality optical flat is placed on top of a polished substrate and used in conjunction with a monochromatic light source light bands are formed. The light bands that are present are known as interference fringes and their shape represents how flat the part being tested measures. Dependent on how many rings are formed or how straight the presented lines are is an indication of how flat the tested part is. Optical flats are used for testing gauge blocks. Optical flats are also used in interferometers and high quality flat optical mirror and window sub-straights for laser applications. This range of quartz optical flats are single-sided. Quartz has low thermal expansion properties and is very durable and cost effective solution over UV grade fused silica. Read PDFs for more information

Knight Optical can offer Meniscus Lenses for use within Optical Systems. We supply a range of Meniscus 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. Any spherical surface will introduce spherical aberrations to an optical system. Meniscus lenses are designed with the curvatures of the lens in mind to minimise these spherical aberrations. This effect is more noticeable with higher index glasses as spherical aberrations increase with the change in index. Meniscus lenses can be an effective compromise on cost and aberration when compared to using aspheric lenses or multiple lens. Fore more information read the PDF….

Monochromatic lights have a low pressure sodium light source that emits monochromatic light in which rays have virtually the same wavelength. This light is a very effective way of viewing fringe patterns on the surface of optical flats (Newton rings) Knight Optical's standard type moonlight has a straight line engraved across the diffused screen enabling the operator to easily compare the straight lines of the component being tested thus identifying how flat the flatness is. Other options of monochromatic lights are available enhanced version and floor standing version. These lights are not supplied with the optical flat as standard however we stock a range of quartz and Zerodur optical flats with a range of flatness’s to meet your application. Monochromatic light units are suitable for the following electrical services: 220/240V, 110V and 12VDC on selected units. Contact our technical team for further information. FOR MORE INFO READ PDF…

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.

With the chip-removing microstructuring of metal surfaces, LT Ultra offers the right manufacturing technology for the production of embossing tools with optical surface qualities that allow economical replication in large numbers. Examples of microstructuring are the production of microfluidics or microlenses on our ultra-precise multi-axis machines. We can manufacture the structures directly in various materials such as brass, chemically deposited nickel or in selected hardened steels.For the replicating production of optical components, ultra-precise mold inserts made of steel are of particular interest due to their very long service life compared to other materials. In order to avoid the final polishing, which often leads to an undesirable change in shape or which is impossible due to a high structure density, LT Ultra offers ultrasound-assisted machining of steels with geometrically defined cutting edges made of monocrystalline diamond.

LT Ultra is your partner for the production of optical surface qualities in injection mold inserts. For example, we can manufacture inserts for the injection molding of spectacle lenses with several focal lengths as well as mold inserts for microlenses or components for vehicle lighting systems. In addition to simple geometries such as spheres or aspheres, we mainly manufacture non-rotationally symmetrical components and freeform surfaces.Mold inserts for a long service life can be made from chemically deposited nickel (NiP). Here you can work directly in the nickel. The advantage is that the very durable nickel can also be deposited on substrates that could not be brought into optical quality themselves or only with great effort. On request, LT Ultra offers the complete delivery of the mold insert as well as the processing of additional parts.

Specially developed for the conditions in final assembly, the automated optical measuring system CALIPRI CB20 measures gap and flush with the highest precision and repeatability, even on poorly or excessively reflective surfaces. The key to this is the patented CaliBreezeTM technology, which uses a thin layer of condensed water to optimize the optical properties of different surfaces for measurement. After the measurement, which only takes a few seconds, the condensation layer disappears without residue. CALIPRI CB20 integrates two patented technologies: CaliBreezeTM technology and the Calipri principle. The latter is a technology renowned in the industry and already integrated in all other CALIPRI solutions from Nextsense. Thus, the cross-platform measurement specifications allow the comparison of the measurement data of all CALIPRI solutions, which simplifies the optimization of production processes.
