Polytec was founded in 1967 to distribute commercial laser technology to industrial and research markets. Building on the company’s early success, Polytec began to develop and manufacture and then manufactured, innovative laser-based test and measurement instruments in the 1970’s. These products have become known around the world as the gold standard in non-contact, laser-based measurement of vibration, speed and length. Advanced product development remains a core strategic activity at Polytec with new electro-optical systems being designed for analytical process measurement, noise analysis, and factory automation.
Polytec develops state-of-the-art laser-Doppler vibrometers and velocimeters designed to solve our customers’ difficult manufacturing, development and research challenges. Polytec vibration analysis systems, length and speed sensors for production processes or optical surface profiling systems support high-quality research, development and manufacturing processes worldwide.
Polytec also distributes, markets, sells and services sophisticated opto-electronic systems and components in select European countries. Besides, Polytec provides analytical measuring systems as an over-all solution for diverse applications in R&D laboratories, for process control and monitoring in industrial facilities.

For more than 25 years, LLA Instruments GmbH & Co. KG (LLA) develops and manufactures analytical technology for chemical imaging in process and laboratory usage. UV-VIS and NIR spectrometer by LLA are utilised worldwide for the analysis and sorting of material streams e.g. waste separation in recycling. LLA technology enables the identification of PVC in PET-flakes sorting or identification of extraneous material in paper recycling at maximum efficiency. In addition, the imaging UV-VIS and NIR spectrometers are also used in C & D recycling, minerals and food sorting. The product portfolio includes hyperspectral cameras as well as multiplexed NIR spectrometer. Newly developed XRF detection system for metal sorting applications is also available from now. Further accessories such as illumination units, software package, RGB line scan camera and comprehensive support complete the portfolio of LLA. The rugged product design is ideally suited for use in harsh environmental conditions. For standard applications, LLA provides ready-to-use analysis routines. Based on LLA's longtime experience, further applications can be developed and customised for new sensor-based sorting applications.
