Photodétecteur 200 MHz à gain variable

Numéro de référence fabricant :


Fabricant FEMTO


Description :

The new high-speed photoreceiver OE-300 with variable transimpedance gain from 102 to 108 V/A offers an exceptionally wide application range. Various models equipped with InGaAs or Si photodiodes cover the 320 nm to 1700 nm wavelength range. The switchable gain from 02 to 108 V/A (decade increments) allows precise and reliable measurements within a very wide dynamic range from nanowatts up to 10 milliwatts optical power.

Many additional features like switchable low-pass filters, offset adjustment, switchable AC/DC coupling and the capability of manual and opto-isolated remote control by a PC make the OE-300 the most versatile wideband photoreceiver in its class.
