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.Features- 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.
