The function of our spectrometer electronics is to convert the analog video signal from the diode-array detector to a robust digital signal that can be read out over a standard interface (like USB or SPI).
The specific electronics you need depend on which detector your spectrometer is equipped with. The detector is given by the three digits in the product name. For example, the FREEDOM FSV-101 uses the CMOS S11639 detector (101).
Below you can see which electronics go with each type of detector. For some spectrometers, we also offer the option to deliver the spectrometer without electronics such that you can develop your own.
