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.

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.

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

No lens element leaves our factory before it meets the exact specifications and requirements of the customer

In various chemical or physical and technical processes particles of the order of 1 μm up to a few mm in size appear, whose size distribution is decisive or important for the process. There are many technical examples like in food production, pharmacy, process engineering, fuel burning in turbines, motors etc., slurry burning, and cosmetics. The laser diffraction particle sizer is capable to measure a particle size distribution from a collective of particles like a spray and to appropriately process, describe, and present it. The particle material may be solid or liquid in a gas or gas like air bubbles in a liquid. For the measurement it is only important, that the optical properties of the continuous and the dispersed phase are different. The laser diffraction particle sizer offers the advantage of a fast and non invasive measurement in a wide range of particle sizes. Especially in case of sprays or suspensions this method has become a standard measurement tool.

Particle size measurements are important in various applied sciences and in engineering, for example in fuel burning or in cavitation research as well as in particle size control. In all these applications it necessary to have knowledge about the particle dynamics. To gain that knowledge one has to measure the particle size and its velocity if possible in a noninvasive way with high local and temporal resolutions. A device which makes such measurements possible is the so called PhaseDopplerAnemometer (PDA), which has several advantages. First, it exhibits a large dynamic range from micrometer particles up to sizes in the millimetre range. Then it is very precise and no calibration procedure is necessary. Moreover, it is very robust against optical distortions. In the following the working principle of this flow and particle measurement technique will be explained.

The measurement technique of LaserDopplerVelocimetry (LDV) is one of the most frequently applied modern measurement techniques in fluid mechanics to perform accurate local flow velocity measurements, which exhibits the advantage of a very high local and temporal resolution. Our technical department offers excellent conditions to perform such measurements (LDV).

You can be assured that we will find the optimal solution for your specific problem based on our experience in the field of optics design. Optical imaging systems, laser optics and illumination systems can be measured and dimensioned with Zemax© OpticStudio 15. The 3D data of the optical design is transferred via an interface to the 3D CAD Product Design Program Inventor and with the support of Inventor the fitting mechanical solution is developed

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.

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.

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.
