C16767MA is mems-based, and sensitive across 190 to 440nm with a typical resolution of 5.5nm (FWHM, so ±2.25nm to 50%).
Vital statistics are 20.1 x 12.5 x 10.1mm and 5g.
“For example, C16767MA can be mounted in water quality monitors, analysing the content of multiple types of pollutants in water via absorption spectrophotometry,” said the company. It “gives good results in measuring nitrite, nitric acid and biochemical oxygen demand level”. Measuring anthracene, added Hamamatsu, it achieved results comparable to those from a benchtop spectrophotometer.
Earlier spectrometers in the micro series have been sensitive to UV, but any incident UV gradually lowered the image sensor sensitivity.
“To cope with this issue, we improved the image sensor photosensitive area to boost its resistance to UV light and optimised the shape of the diffraction grating – spectral resolution was improved by shrinking the groove spacing to ~500nm,” said Hamamatsu. “To keep stray light out of the image sensor, we formed a silicon nitride thin film on the image sensor by applying our unique in-house opto-semiconductor device manufacturing technology.”
C16767MA will be on display at Photon Fair 2023, the company’s three-day in-house exhibition at Act City Hamamatsu, starting Thursday 16 November.
