FEMTO's 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 it’s free space input option.  FC and SMA optical fiber inputs are also an option.  The OE-300 is part of a full line of Signal Recover Amplifiers from FEMTO with the best performance available.  They are also small in size so you can get them close to your work.
