Amplifiers
Amplifiers are used to amplify the energy output of photodetectors as well as convert their electrical signal for a number of illumination measurement or spectroscopy applications. Amplifiers are digital systems that amplify the low electrical current transmitted by photodetectors to easily detectable levels. Amplifiers also convert photodetectors' electrical current into voltage so that their signal may be read by other digital devices. Amplifiers are indispensable for nearly any light measurement applications by greatly increasing the usability of a detector system.

Single Channel Potentiostats
Potentiostats control a voltage and measure a resulting current. The Control Amplifier outputs power to the counter electrode (also called auxiliary electrode). A feedback loop is established to control the cell potential between the reference and working electrode. This voltage is measured by the input electrometer, that has a high impedance. This current is then measured between the working and counter electrodes while this potential is maintained at the working electrode and reference electrode.
