Lock-In Amplifiers

Lock-in amplifier are used to detect very small signals at a given frequency, even if the noise level seems higher than the signal itself. The lock-in amplifiers we propose are analog devices that are easy to use, extremely compacts and at an affordable price. These units are perfect to measure , among other applications, optically chopped signals for very low light levels. Optical detectors can be directly coupled to the lock-in amplifiers since these provides current or voltage inputs.
