Product Details Supplier Info More products

Laser Components is offering voltage, current and lock-in amplifiers from Femto. They are said to provide sophisticated methods for detector pre-amplification and transient measurements among other applications.

Certain parameters across the range of amplifiers can be customised, enabling the company to provide devices tailored to suit customer requirements.

Range information

  • Variable (gain 10–60dB), logarithmic (up to 80dB) and wideband (DC to 10MHz, 200MHz or 500MHz) voltage amplifiers are available
  • Low-frequency devices include the control of gain settings and bandwidth by switches directly on the amplifier
  • The dependence on the gain setting with the bandwidth is minimised, allowing rise/fall times to remain constant across the gain settings
  • Ultra-low-noise (0.18fA/√Hz), high-band-width (400kHz) and high-gain (10E13V/A) current amplifiers are available
  • These modules are small and offer short electrical connections to the detector, before the signal-to-noise ratio significantly decreases due to cable capacitance and noise pickup
  • Optoelectronic systems utilise lock-in amplification as one of the most useful techniques to remote unwanted noise, therefore improving measurement sensitivity
  • The modules operate reliably even in extremely noisy environments
  • Phase, gain and time constant are controlled either by switches directly on the amplifier module or externally using a standard digital I/O computer board
