High Performance lock-in amplifier at an attractive price
The high prices for usual desktop lock-in-amplifiers often impede their use in cost sensitive applications. For this reason, FEMTO designed a complete and easy-to-use lock-in board at a very attractive price. All settings for sensitivity, time constant and phase shift can be selected either manually by front-panel switches or remotely by a PC via the digital interface. Additional signal filters can be configured by jumpers on the board to further increase the dynamic reserve in demanding applications.
19" Board versus PC Card
A PC card is exposed to
the electromagnetic disturbed environment inside a computer case.
Therefore, using a PC card for ultra-sensitive measurements of small
signals is often not practical. FEMTO's Series
Applications
- Spectroscopy
- Luminescence, Fluorescence, Phosphorescence Measurements
- Light Scattering Measurements
- Opto-Electronical Quality Control
- Integration in Industrial and Scientific Measurement-Systems
- Multi-Channel-Systems at an Attractive Price
