Hamamatsu mini spectrometers are polychromators integrated with optical elements, an image sensor and a driver circuit. By merging our unique image sensor technology, accumulated over many years, with advanced MEMS technology such as holographic processing, Hamamatsu has developed spectrometers featuring a compact size and low cost.
Hamamatsu mini spectrometers leverage four versatile optical designs and MEMS-etched holographic transmission gratings to create innovative performance.
Mini spectrometers employ either a CMOS or NMOS linear image sensor or a BT-CCD detector. CMOS and NMOS detectors are well-suited for spectrophotometry at relatively high light levels such as absorbance measurement and light source spectrum evaluation. High-sensitivity mini spectrometers using a back-thinned CCD image sensor as the detector are ideal for low-light-level spectrophotometry applications such as fluorescence, Raman, and atomic emission measurements.
Spectrometer Applications
- UV to VIS (200 to 1100 nm): light source testing (LEDs), fluorescence measurement, industrial color measurement, tooth decay analysis, detection of saccharic acids in food, taste analyzers, semiconductor inspection, chromatography, and DNA analysis
- NIR (900 to 2550 nm): process control instrumentation, component analysis (food, agriculture, etc.), water content measurement, optical communication component testing, film thickness measurement (white light interferometry), agriculture
