Compact und configurable infrared spectrometer based on the latest MEMS technology for being used in online monitoring processes
 Request for information
Application
Polymer industry
- plastic identification during recycling processes
- process control during polymerization
- thin film measurement
Organic chemistry
- determining stationary endpoints of different reactions (esterification)
- identification and classification of raw materials
Food industry
- moisture measurement after evaporation or drying
- determining fat and water content in milk, butter, etc.
- determining alcohol in beer, wine and spirits
- identification of unsaturated acid
Unlike to traditional spectrometers the getSpec NIR 0121 MEMS does not use a detector array but single detectors. This is realized by micro electro mechanical systems (MEMS). The spectrometer principle is based on dispersive array spectrometers. A micro mirror serves as main component allowing to periodically direct spectral parts dispersed by diffraction gratings to the single detectors.
The preprocessing of spectral data is realized by integrated logic components transmitted to PC via USB or RS 485 interface. Those data is displayed and treated by application software. Specific requirements (OEM) can be respected by firmware adaption.
Advantage
- compact, transportable and reasonable
- free configurable (wavelength, spectral resolution)
- fast measurement cycles (primary measurement period 2ms) allow real time measurements
- high tolerances
- flexible (coupling to fiber optics)
- universal application due to different measurement geometries
Software
The operating software controls the spectrometer module and visualizes detected spectra. Besides displaying spectra over certain wavelengths or displaying wave numbers, simple spectral operations such as offset drift correction or referencing spectra are possible.
Those measured spectra can be saved on demand separately or in a common matrix as ASCII files (other exports and/or connections to other systems possible on request). The software is parameterized by a module specific INI file.
Operating system: Windows 2000, XP, Vista, Linux (projected)
