C12666MA

Fingertip size, ultra-compact spectrometer head integrating MEMS and image sensor technologies

 

The C12666MA is an ultra-compact (fingertip 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.

- 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.

Measurement example

Color measurement

A demonstration module with a built-in the mini-spectrometer Micro series was used to measure the spectrum of color sample. Because the Micro series is small, it can be mounted on various color measuring devices such as color adjustment of color printers and dimming of LED lighting.

Application examples

Features

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.
