Mini spectrometer module targets inline testing

The latest offering from Hamamatsu Photonics in its range of miniature spectrometers is the C11697MB; a high-sensitivity, trigger-compatible VIS-NIR mini-spectrometer module. The new module is ideal for inline testing applications and measurement of pulsed light emission due to the high sensitivity offered by the new S11639 CMOS linear image sensor housed inside.

The C11697MB offers high sensitivity across a wide spectral response range from 320 - 1000 nm, with light input from the measurement sample via a fibre optic cable. With a 2048 pixel array offering a spectral resolution of 8 nm, the module offers a high-speed readout time of only 2 ms.

Along with the trigger function of the CMOS array offering an integration time of only 30 µs, this makes it ideally suited for inline inspection of LEDs.

Operation of the spectrometer is simply via a USB interface which enables “plug and play” connection to a PC, so no external power supply is required.

It comes supplied with free evaluation software that allows the user to set the measurement conditions, acquire and save data and display the results graphically. This makes it very easy to set up and begin taking basic measurements.
