Mini-spectrometer micro series



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.

- Finger-tip size: 20.1 × 12.5 × 10.1 mm
- Weight: 5 g
- Spectral response range: 340 to 780 nm
- Spectral resolution: 15 nm max.
- Hermetic package: High reliability against humidity
- Installation into mobile measurement equipment
- Wavelength conversion factor is listed on test result sheet.

Application examples



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.
