2-channel sensor systems SPECTRO-2
The SPECTRO-2 system can operate as a pure 2-channel system (quasi two SPECTRO-1 sensors in one housing), or as a comparative (normed) system in which one channel can function as a reference.
High-frequency contrast sensors SPECTRO-1
The SPECTRO-1 sensors are contrast sensors that are able to record even slightest brightness differences almost in real time.
