FEMTO Introduces a 200 MHZ Variable Gain Photoreceiver
FEMTO’s new 200MHz high-speed photoreceiver OE-300 has variable gain from 102 to 108 V/A.  Equipped with InGaAs or Si photodiodes it covers 320 to 1,700 nm wavelength range.
The OE-300 photoreceiver series uses premium quality photodiodes followed by a high-end, variable gain transimpedance amplifier. The low noise performance (NEP) is outstanding and the relatively large sized detectors make optical alignment easy.
It has switchable gain from 102 to 108 V/A giving precise and reliable measurements within a wide dynamic range from nanowatts up to 10 milliwatts optical power.
The OE-300 works with standard optical accessories like tubes and lenses using the free space input option. FC and SMA optical fiber inputs are an option. The OE-300 models can be easily mounted to standard optical post holders using a plate option.
