Fur coats - Import export

Coating substrates is one of our core competences. We have been coating precision optic components with optically effective layers ever since 1948. Over the years, technical specifications and possibilities have radically changed. We now have several highvacuum plants, an ultrasound cleaning and drying plant at our disposal to treat the substrates. We also build our own equipment e.g. for asymmetrical prisms. Coated substrates are inspected and documented with a "Lambda 900" PE spectral photometer. Antireflection coatings

Our product range comprises objectives with focal lengths from 5 60 mm. Our objectives are all coated with a reflectionreducing coating and are computed and optimized for the intended application. Of course, we also design and compute customized objectives and systems to meet your special requirements.

Reflectionreducing coatings increase the light transmission of optical systems. This is particularly important for the light intensity of multilens optical systems such as objectives. Another benefit of antireflection coatings is their capability to strongly reduce scattered light losses between the lenses. Our product portfolio covers single and multiplelayer antireflection coatings, antireflection coatings for laser applications and coatings for applications in ultraviolet (UV), visual (VIS) and infrared (IR).

Befort Wetzlar is mentioned and recommended in the relevant Internet forums as a coater of telescope mirrors. We serve customers in astronomy, natural sciences and technology, supporting users with our technical knowhow. After all, you can't enjoy the best possible view of the universe without maximum reflectivity and robust mirrors.

The deflection and separation of light beams in different intensities, directions or wavelength ranges can also be controlled by thinfilm vaporization. Either a metallic or a dielectric coating is chosen, depending on requirements and application. The abovementioned advantages of dielectric reflection coatings play a decisive role here, too.

Compared with conventional metallic reflection coatings, the advantages of dielectric reflection coatings are their climate resistance, mechanical stability and high reflection combined with relatively low absorption. These properties are crucially important for many optical applications involving extreme thermal and mechanical stress.

Metallic thinfilm systems are vaporized onto substrates to attain specific reflection and transmission values. Depending on the type of metal and the thickness of the layer, metallic splitter coatings are able to separate customerspecific wavelength areas.

Metallic reflection coatings enhance reflection and are used in many optical instruments for light deflection. We coat glass, metal and plastic. The choice of coating material depends on the reflection requirements in the defined wavelength range. We use aluminium, gold, silver and chromenickel, either with or without protection coating for the VIS, UV and IR ranges.

Befort VIS objectives are colorcorrected for VIS use and are routinely equipped with VISAR coating. The UV objectives are made of quartz glass or CaFl2 and optimized for λ = 185 nm

Mixing Bulk material processing with convincing results With our mixing systems homogeneous mixtures and coatings are produced from various bulk material. This is enabled by our cutting-edge mixing machinery which includes drum mixers, container mixers, Nauta Mixers, high-speed mixers, Rhönrad mixers, swivel screw mixers and other special mixing systems. Modern machinery guarantees quality The mixing machinery at Ebbecke is supplemented by a fully automatic gravimetric load cell weighing plant, as well as by a chopper, nozzle fittings and equipping possibilities for various containers. Technically, Ebbecke Verfahrenstechnik AG is thus equipped for every task imaginable in the area of contract mixing, even for contract mixing of particularly shear-sensitive bulk material. The quality of our mixing machinery proves itself in the technical details: Product-contacting parts consistently made of stainless steel in accordance with the current hygiene standards. Furthermore, all mixing sys
