Amplified Photodetector, Biased, AC coupled, 1475–2100 nm, Ext. InGaAs, 10 GHz

The 818-BB-51A High Speed Amplified Biased Photodetector is built from a free-space extended InGaAs photodiode with a 40 μm active diameter and a fast <35 ps rise time. With the wavelength range of 1475 - 2100 nm, it allows monitoring Thulium (Tm) and Holmium (Ho) doped lasers as well as other NIR lasers. It has a built-in amplifier with approximately 26 dB of gain. The detector is AC coupled and features a bandwidth of up to 10 GHz. A wall plug-in style power supply is provided with this unit.
