Ultra-compact mini-spectrometer integrating MEMS and image sensor technologies



The MS series are thumb-sized (27.6 × 13 × 16.8 mm) spectrometer heads developed for installation into mobile measurement equipment by merging our MEMS and image sensor technologies. The MS series use a CMOS image sensor integrated with a light receiving slit. The internal optical system is comprised of a convex lens on which a grating is formed by nanoimprint. The result is a remarkably small size less than one-third the volume of the RC series mini-spectrometers that have already been marketed.
