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.
Program the Lock-in amplifier 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
Available:
- Low Noise Input/Output Cable: CAB-LN1 Low Noise Cable
- The LUCI-10 amplifier interface allows remote control of FEMTO amplifiers and photoreceivers with a remote control capability from a standard Windows PC with USB port.
