Unlike metallic splitter coatings, dielectric splitter coatings enable absorptionfree light conditions. Dielectric splitter coatings are used in various filters and particularly in laser technology and reference metrology.

Befort measuring microscopes are robust, flexible usable and are optimally suited for daily use in a tough production environment. The handling of the measuring microscopes is easy and their image quality is impressive

The 6, 8 and 10fold Befort magnifiers have been THE magnifiers for precise reading for 30 years. All measuring magnifiers have metal engraved scales. The measuring plates are manufactured and surfacetreated individually using a special process. This timeconsuming precise manufacturing guarantees parallaxfree reading when the magnifier is directly positioned on the object to be measured.

Achromatic systems consist of two single lenses of different refraction that are cemented together. This avoids the inherent achromatic aberrations of single lenses that lead to blurred or distorted images. We produce these highquality optics with diameters of 10 50 mm and focal lengths of 20 250 mm. We supply black anodized aluminium mounts with all achromatic systems on request.

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.

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)

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 orthoscopic oculars create a fast, low distortion image and may optionally be equipped with various eyepieces (line or crosshair graticules, scales or circles).

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

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

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

At Befort, spherical precision optics pass through the hands of qualified specialists. They work with a sure instinct and stateoftheart technology.

The liquid lens objective is an Smount objective with internal focusing on the basis of a liquid lens. The working distance can be electronically set by applying voltage. This procedure makes mechanical components completely obsolete. The objective’s design is compact and robust. The objective has excellent optical properties and is ideally suited for observation or image processing tasks. Focal length and mounting thread can be adjusted to customer specifications.
