Mini-spectrometer MS series

C10988MA

Ultra-compact Mini-spectrometer integrating MEMS and image sensor technologies The MS series C10988MA is a thumb-sized (27.6 × 13 × 16.8 mm) spectrometer head developed for installation into mobile measurement equipment by merging our MEMS and image sensor technologies. The MS series uses 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.

Note: The clock pulse should be set from high to low just once when the start pulse is low. The internal shift register starts operating at this timing. The integration time is determined by the start pulse intervals. However, since the charge integration of each pixel is carried out between the signal readout of that pixel and the next signal readout of the same pixel, the start time of charge integration differs depending on each pixel. In addition, the next start pulse cannot be input until signal readout from all pixels is completed. Video output is 1/4 of the clock pulse frequency.

Evaluation circuit C11351 for mini-spectrometer MS series The C11351 is a circuit board designed to simply evaluate characteristics of minispectrometer C10988MA. By using the C11351 with the C10988MA (sold separately) and a USB cable A9160 (AB type; sold separately), the C10988MA characteristics can be evaluated with the dedicated software.

Features Initial evaluation circuit for C10988MA Wavelength conversion factors of C10988MA can be input from PC*1 High A/D resolution (16 bits) Powered only via USB port *1: A wavelength conversion factor for converting the image sensor pixel number into a wavelength is recorded in C11351. To measure a spectrum with higher wavelength accuracy, it is necessary to input the wavelength conversion factor listed in the final inspection sheet that comes with each C10988MA.
