Lock-In-Amplifier as a Standard
The high prices for usual desktop lock-in amplifiers mean that they are not as common in noise limited experiments as would be desirable. For this reason FEMTO designed a complete, easy-to-use and high performance lock-in amplifier expanding the reach of lock-in amplifiers into cost-sensitive applications.
Programming the Lock-In Manually or by Computer
The Series LIA-MV(D)-200 Lock-In Amplifiers are designed as stand-alone units which can be programmed both manually by front-panel switches and remotely by a digital interface. By using a PC with a standard digital I/O card all main settings for sensitivity, time constant and phase shift can easily be controlled. Therefore, the Series LIA-MV(D)-200 Lock-In Amplifiers are the ideal tool for integration into complex or automated test systems as well as for use as standard lab unit in cost-sensitive applications.
Applications
Spectroscopy
Luminescence, fluorescence, phosphorescence measurements
Light scattering measurements
Laser stabilization
Opto-electronical quality control
Integration into industrial and scientific measurement-systems
Alternative to expensive desktop lock-in amplifiers for general lab use
