SDCM4

Readout electronics

The SDCM4 Line-Array-Sensor readout electronics is a highly integrated, modular operation platform for miniature spectrometers and integrated systems with optional thermo-electrical sensor cooling. All sensors are supported by the universal version with additional sensor PCB. Specific ones are available as economic one board solutions.
