 Beam analysing systems are necessary in order to achieve information about the spatial intensity distribution or phase in the cross section of a laser beam. There are two different measurement principles to distinguish - camera based systems and scanning-slit systems. Both are available for lab applications as well as for system integration.  Optical position sensing detectors are ideal for contact-free measurement of positions and angles. They are used in many areas like life sciences, industry, control engineering and quality assurance. Typical applications are adjustment and alignment of lasers and the automated detection and tracking of machine elements.  Optical power is measured precisely by semiconductor sensors as well as by volume or surface absorbing detectors. Pyroelectric detectors are used to measure pulse energies. Several display units are available to provide the best solution for every kind of application. OEM components enable an easy system integration of power and energy measurements.  Photometry relates the measured radiation power to the visual response of the human eye. It emulates the spectral sensitivity to light of the eye by means of special transmission filters in front of the detector.The calibration of these detectors is performed in lux, cd/m˛ or footlambert. The task of colorimetry or color measurement is to numerically describe the result of a visual color inspection or color comparism.  The use of monochromators and spectrometer systems for UV to IR in combination with customized software for spectral analysis allows these frequency ranges to be detected and graphically displayed with ultra-high resolution. Main applications include the evaluation of spectral behavior and average wave length as well as the measurement of transmission, reflexion and color coordinates. |
 By the use of the latest physical process technology a new generation of cameras is available providing extremely high light amplification which makes them suitable for weak light intensity applications. A special CMOS sensor combines all the advantages of a CCD sensor, like highest quantum efficiency, low noise and flexible read-out areas with a high read-out rate, small footprint and low power consumption.  Integrating spheres are multifunctional and deliver highly precise measurement results in the area of light measurement. Equipped with individual illumination and several patented coatings, the spheres can also be used as homogeneous radiators. This product line is complemented by complete UV measurement systems and LED measuring stations.  Many adjustment applications require the conversion of invisible IR or UV radiation to visible light. Affordable tools for this kind of applications are handheld viewers based on converter tubes. For fast and easy detection of beam locations there are sensor cards available, optimized for certain wavelength and power ranges.  For measuring the time response of optical signals or relative signal powers you can choose from a broad portfolio of detectors, each optimized for a certain application. Ranging from simple photo diodes or combined systems with appropriate amplifiers in the standard and high-speed range up to complex measuring stations, you can be sure to find the best solution for your need.  In many areas it is essential to obtain reliable information about the temperature and its temporal behavior. In some cases conventional electrical thermometers like resistance thermometers or thermocouples fail, e.g. due to strong electromagnetic interference. Here the fiber based thermometry plays off its advantages. By measuring the decay of a fluorescence at the tip of a fiber the temperature can be determined very precisely. |
