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 mea-
surement 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.

*2: Depends on the slit opening. Values were measured with the slit listed in the table “ Structure / Absolute maximum ratings”.
*3: Measured under constant light input conditions
*4: When monochromatic light of the following wavelengths is input, spectral stray light is defined as the ratio of the count measured at
the input wavelength, to the count measured in a region of the input wavelength ±40 nm.

*5: An increase in the current consumption at the video output terminal also increases the chip temperature and so causes the dark
current to rise. 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.
