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.

Optics are rarely standalone components. They frequently need a casing, a carrier or even complex integration into a system. This is the exact specialty of our Mechanical Engineering department. We put our mechanical production skills in the service of optomechanical and even purely mechanical customer applications. We manufacture nonferrous metal, noncorroding machininggrade steel and plastic components and produce highprecision mechanical subassemblies as well as unmounted turned and milled parts in small and medium quantities. CNCmanufacturing of turning and milled parts CNCmanufacturing with driven tools CNCMilling machine with 3 and 5axis also in single and small series production Prototypes (max. turning diameter up to 60 mm and milled parts 500 x 400 x 100 mm)

Finest quality surface polishing is vital in plane optic production. At Befort, this has top priority from production all the way to final inspection. Thanks to sophisticated CNC technology, we are able to produce single planeoptic components as well as multifunctional systems. We process optical glass, filter glass, quartz glass and float glass up to a size of 600 mm diameter. We make filters, groundglass screens, plane mirrors, windows with a plane parallel surface contour and realize customized solutions for specific applications. In our test laboratory we measure machined surfaces with an interferometer to be able to guarantee top optical quality! No lens element leaves our factory before it meets the exact specifications and requirements of the customer

Modern Defense, Aerospace and NewSpace customers require high performance optical systems which minimize Size, Weight and Power (SWaP) while maximizing optical performance. One proven technique for achieving demanding SWaP requirements is to require light-weighted optics. Light-weighting is a process by which material is removed from the optical component by machining or other methods while preserving the optical performance. This is often performed with low-expansion ceramics and glasses, and careful attention must be paid to the light-weighting structure to ensure optical performance and rigidity. ZYGO experts are available to assist in our partners design of these components for manufacturability.
