C12666MA
Finger-tip size, ultra-compact spectrometer head
integrating MEMS and image sensor technologies
The C12666MA is an ultra-compact (Finger-tip size) spectrometer head developed based on our MEMS and image sensor
technologies. The adoption of a newly designed optical system has achieved a remarkably small size, less than half the volume of the previous mini-spectrometer MS series (C10988MA-01). In addition, the employment of hermetic packaging has
improved humidity resistance.
This product is suitable for integration into a variety of devices, such as integration into printers and hand-held color
monitoring devices that require color management. It is also suitable for applications that collaborate with portable
devices, such as smartphones and tablets.

*4: 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.

Optical component layout
Besides a CMOS image sensor chip integrated with an optical slit by etching
technology, the C12666MA employs a reflective concave blazed grating formed
by nanoimprint. In addition, the glass used in the light path of the previous
C10988MA-01 is not used in the C12666MA, making it extremely compact.

A/D output is the output with dark output is subtracted
when light is input. The difference between the ideal value
and typical example contains a measurement error. The
smaller the A/D output, the larger the measurement error.
A/D output is the sum of the sensor and circuit
offset outputs and the sensor dark output.

Precautions
· The packaging of C12666MA is electrically conductive, so be careful when designing the circuit to avoid short circuit caused by contact
with a circuit pattern.
· If external force is repeatedly applied to the lead pins, this may damage the lead pins.
· To prevent damage due to soldering, be careful of the soldering temperature and time.
As a general guide, finish soldering within 3.5 seconds at 350 °C or less when soldering by hand, or within 10 seconds at 260 °C or less
when using a solder bath.

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.

Micro-spectrometer evaluation circuit C11351-10 (sold separately)
The C11351-10 is a circuit board designed to simply evaluate the characteristics
of the micro-spectrometer. The characteristics of the micro-spectrometer can be
evaluated using the evaluation software by connecting the micro-spectrometer
to a PC with a USB cable A9160 (AB type, sold separately)*10.
Features
Initial evaluation circuit for micro-spectrometer*11
Wavelength conversion factors of the micro-spectrometer
can be input from a PC.*12

USB powered
*10: Compatible OS:
Microsoft® Windows® 7 Professional SP1 (32-bit, 64-bit), Microsoft® Windows® 8 Professional (32-bit, 64-bit)
*11: The C11351-10 is a modified version of the C11351 evaluation circuit for the previous mini-spectrometer MS series (C10988MA-01,
C11708MA). Only the sensor board has been modified. If you already have the C11351, you only have to purchase the C11351-03 (the sensor board for micro-spectrometers) to evaluate C12666MA micro-spectrometers.
*12: A typical wavelength conversion factor is entered at the time of shipment of the C11351-10. 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
micro-spectrometer.
Note: Since the C11351-10 is an evaluation circuit for the micro-spectrometer, the DLL function specifications are not available to users.
