Projects and contract development

R&D and Product Development

TEM Messtechnik right from the beginning aimed at the development of special solutions for scientific and industrial applications in physics, chemistry and medicine:

  • Measurement and control systems
  • Data recording and processing
  • Diode laser systems
  • Optoelectronics
  • Laser stabilization
  • High precision mechanics

The development process goes from the first idea to the production-ready solution. It includes customer specific adaption of the standard products, the development of new electronic devices, analog and digital solutions, OEM boards, modular system or stand-alone devices.A focal point is on the high precision and fast regulators for the resonator length (or wavelength selection elements inside of the resonator) of tunable lasers and thus for the wavelength of the emitted light.

The employed interferometric and spectroscopical wavelength sensors belong to the products of TEM Messtechnik as well as: PID regulators, lock-in regulators, RF modulation techniques, current sources, temperature controllers, scan generators →, high voltage piezo amplifiers →, photo diode amplifiers →, automatic fiber couplers →. The interferometrically controlled, 1000GHz mode-hop free tuning of DFB-laser diodes is an example for these activities.

Another core area is the development of control systems for positioning of laser beams (Aligna® →). The end user group ranges from those who employ the Aligna for high precision material processing to research institutions where the stabilization of the laser beam opens new experimental possibilities.
