November 6, 2011 - The C11708MA miniature spectrometer offers SWNIR sensitivity and ultracompact size. Its small package (27.6 x 13 x 16.8 mm) is easily mounted on a circuit board, so it can be used as a sensor in portable measurement equipment. Constructed using Hamamatsu’s MEMS and optical technologies, the C11708MA features a CMOS linear image sensor integrated with an entrance slit, as well as a grating formed on a convex lens by nanoimprinting.
The CMOS image sensor has 256 pixels, each measuring 12.5 x 1000 µm. The image sensors spectral sensitivity ranges from 640 nm to 1050 nm, and its high SWNIR sensitivity is suitable for analyzing food contents and other materials. Other features include a spectral resolution of 20 nm. An evaluation circuit board, the C11351, is available (sold separately) for easily evaluating the characteristics of the C11708MA.
This circuit board is powered via a USB2.0 connection, has 16-bit A/D conversion, and allows integration times from 5 ms to 10 seconds.
