Mini-spectrometer
C16767MA
Fingertip-sized, ultra-compact spectrometer head supporting high UV sensitivity
The C16767MA is a high-sensitivity, ultra-compact (fingertip-sized) spectrometer head. The C16767MA supports the ultraviolet region (190 to 440 nm). This product is suitable for integration into a variety of compact devices.
Features
- Fingertip size: 20.1 × 12.5 × 10.1 mm
- Weight: 5 g
- Spectral response range: 190 to 440 nm
- High sensitivity
- Spectral resolution: 8 nm max.
- Supports synchronized integration (electronic shutter function)
- For integration into mobile measurement equipment
- Wavelength conversion factor is listed on final inspection sheet.
Application examples
Water quality analysis
Atmospheric analysis (NO, SO2, etc.)
Monitoring UV-LEDs, UV-A, UV-B, and UV-C
Semiconductor process monitor (plasma, gas, etc.)
Features
The C16767MA is a newly lined up mini-spectrometer that employs a CMOS image sensor, in which the slit is integrated by the etching technology, as well as a reflective concave surface grating made by nanoimprint lithography. The C16767MA is equipped with an image sensor with enhanced UV resistance and a diffraction grating optimized for UV diffraction.
In addition, a stray light cut filter, made with our unique opto-semiconductor manufacturing technique, is formed on the image sensor in order to restrain the stray light generated during diffraction from entering into the image sensor.

Measurement examples
The left diagram shows measurement examples of nitric acid, nitrous acid, and BOD (biochemical oxygen demand), which are generally examined in water analysis. It can be understood that favorable results are obtained in the measurement with a demonstration module utilizing C16767MA. In the measurement of organic compound, anthracene, the results equivalent to the table size spectrophotometer is obtained as shown in the middle and right diagrams.
