High Performance 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 LIA-BV(D)-150 Lock-In Amplifiers are designed as 19" boards which can operate in EMI-designed standard cases which offer best possible shielding and noise suppression. In addition, they are the perfect choice for designing high-performance multi-channel systems.
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
