Finger-Nail Sized, Ultra Compact Mini-Spectrometer – Hamamatsu C12666MA

Hamamatsu C12666MA is an ultra-compact spectrometer head, which is designed based on the company’s MEMS and image sensor technologies.

The implementation of a recently designed optical system has resulted in an exceptionally small size (finger-tip size), which is lower than half of the volume of the earlier mini-spectrometer MS series - C10988MA-01. The use of hermetic packaging also provides better humidity resistance.

The C12666MA is suitable for integrating in a wide range of devices, such as mobile color monitoring devices and printers that need color management. The system can also be used for applications that integrate with mobile devices, such as tablets and smartphones.
