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 vol-
ume 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 amplier for impedance conversion to the video output terminal so that the current
ow is minimized. As the buffer amplier, use a JFET or CMOS input operational amplier 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 reective concave brazed 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.
