The mini spectrometer is a product that combines Hamamatsu’s advanced micro-opto-electro-mechanical-systems (MOEMS) technology, which integrates optical technology like MEMS technology, optical systems, and opto-semiconductor devices, along with software and circuits, all in a compact package.
Serving as the heart of the mini-spectrometer, the detector is an industry proven Hamamatsu image sensor designed for measurement and analysis fields. Hamamatsu designs its own grating in house, which is capable of carrying out spectroscopy, and as a result the mini-spectrometers can be mounted with a grating of many specifications, like wide spectral range, high resolution, high diffraction in the ultraviolet (UV) region, etc.

- Color adjustment – Micro-spectrometers, incorporated within color printers and other similar printing systems, track the color of printed materials
- Sugar content measurement – Absorbance can be used in applications like handy brix meters that are capable of determining sugar content
- Film thickness measurement – White light interferometry can be used to measure the film thickness, film refractive index and spectrum peak count from the light incident angle
- Fluorescence measurement – The emission spectra of fluorescent materials, like organic EL devices and fluorescent lamps, can be determined
- Plastic screening – This is carried out by leveraging the fact that when near infrared light (NIR) is focused at plastic, the wavelengths which are absorbed differ based on the material
- Environmental analysis – Mini-spectrometers are utilized in the environmental analysis of soil, water, etc.
