With the new OE-200-BPR, FEMTO is expanding its range of balanced photoreceivers to include bandwidths from DC to 500 kHz and gains up to 1011 V/W.
The OE-200-BPR series photoreceivers / photodetectors consist of the combination of two anti-parallel connected photodiodes with a subsequent low-noise transimpedance amplifier. The low input noise (NEP) together with extremely high common-mode rejection sets standards for balanced photo-receivers in the kHz range and enables highly sensitive signal detection. The total of nine switchable gains allow adaptation to almost any light power from fW to mW and open up a wide range of applications.

Fully compatible with LUCI-M: By connecting the D-Sub 25 plug and socket, the USB control and data acquisition system LUCI-M and the balanced photo-receivers OE-200-BPR a compact unit that acts like a single, remotely controllable measuring system. Between LUCI-M and OE-200-BPR No wiring is necessary, ensuring the setup remains compact and tidy. The overall system offers the following range of functions:
- Reading out the output signal using a 2.5 MS/s ADC
- Switching Gain
- Switch between Low Noise and High Speed
- Switching AC/DC coupling
- Reading out the overload status
- Setting the offset compensation voltage using a DAC
