Mini-spectrometers MS series C10988MA-01 C11708MA Ultra-compact mini-spectrometer integrating MEMS and image sensor technologies The MS series are thumb-sized (27.6 × 16.8 × 13 mm) spectrometer heads 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.

To avoid this, connect a buffer amplifier for impedance conversion to the video output terminal so that the current flow is minimized. As the buffer amplifier, use a JFET or CMOS input operational amplifier of optical input impedance. www.hamamatsu.com 1 Mini-spectrometers MS series C10988MA-01, C11708MA Structure / Absolute maximum ratings Parameter Value 27.6 × 16.8 × 13 9 256 12.5 × 1000 CMOS linear image sensor 75 × 750 0.22 +5 to +50 -20 to +70 Dimensions (W × D × H) Weight Number of pixels Pixel size (H × V) Image sensor Slit*6 (H × V) NA*7 Operating temperature*8 Storage temperature*8 Unit mm g pixels μm μm °C °C *6: Entrance slit aperture size *7: Numeric aperture (solid angle) *8: No dew condensation When there is a temperature difference between a product and the surrounding area in high humidity environment, dew condensation may occur on the product surface.

Optical component layout (C10988MA-01) Besides a CMOS image sensor chip integrated with an optical slit by etching, the C10988MA-01 employs a grating that is formed on a convex lens by nano-imprint.

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. 6 Mini-spectrometers MS series C10988MA-01, C11708MA Recommended driver circuit example Vdd C10988MA-01, C11708MA Gain 6 Gain CLK ST EOS Timing generator 1 CLK 4 ST 7 EOS Digital buffer A/D converter Vdd 9 2 Analog arithmetic circuit * (subtraction, amplification, etc.) + Vdd GND 10 Video * Use as needed KACCC0502ED Evaluation circuit C11351 for mini-spectrometer MS series The C11351 is a circuit board designed to simply evaluate characteristics of minispectrometer MS series.
