Reflective coating - Import export

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.

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).

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.
