Mini-spectrometers are compact spectrometers (polychromators) whose optical system, image sensor, and circuit are condensed into a small case.
Previous spectroscopic instruments used in the chemical analysis field and the like have been typically large and expensive. In contrast, mini-spectrometers are compact and portable, making it possible to take real-time measurements on-site, rather than having to bring in measurement samples into a room in which a spectroscopic instrument is installed.
This miniaturization also made it possible to incorporate them into various types of equipment. They are used in environmental measurement instruments, color measurement instruments, production lines, information devices and so on.
Hamamatsu provides more than 20 types of mini-spectrometers that cover the spectral range from UV to near infrared. Further, Hamamatsu offers ultra-compact types that allow them to be installed in mobile devices and collaborate with portable devices.
