Fraunhofer Institute for Photonic MicrosystemsFraunhofer IPMS is a provider of fully-fledged and at the same time cost-effective grating spectrometers. Compared to the conventional use of expensive detector arrays, our spectrometers are based on an advantageous combination of MEMS technology and inexpensive point detectors. The cost advantage increases significantly towards longer wavelength ranges. In addition, wavelength ranges can be addressed for which no detector lines are available on the market. We cover all areas of the value chain for our customers, from studies, design and draft through to modules and complete systems. Our production capacities enable us to act as a reliable partner from initial samples to pilot production in small, medium and large quantities.

Miniaturized NIR grating spectrometer with the external dimensions
Functionality
Setup of the near-infrared spectrometer.
The radiation to be analyzed enters the spectrometer through an entrance slit and is directed onto a diffraction grating via a collimation mirror and a MEMS mirror. After spectral splitting at the grating, the radiation hits the MEMS mirror again and passes through an exit slit to the detector. The exit slit limits the radiation hitting the detector to a narrow spectral section. Radiation that does not reach the detector is effectively eliminated in the spectrometer using scatter and false light suppression methods. The entire spectral range is presented to the detector in discrete time by rotating the plane mirror in the MEMS. Motorized drive and high-precision deflection sensors are integrated components of the MEMS mirror. Electronics and firmware for operating the MEMS and processing the photocurrent from the detector complete the grating spectrometer.
