General
Low-noise Si or InGaAs photodiodes with a specially designed transimpedance amplifier with extremely high gain of up to 1012 V/A and very low noise. The Femtowatt Photoreceivers series can replace APDs, PMTs and cooled Ge photodiodes in many applications

HBPR 差動平衡式雙輸入光檢測
The photoreceivers / photodetectors of the HBPR series consist of a combination of two anti-parallel connected photodiodes with a subsequent low-noise transimpedance amplifier. The photodiodes are carefully selected and matched in pairs to achieve the highest possible common mode rejection ratio (CMRR). By taking the exact difference between the two input signals, common-mode noise, such as the intensity noise of the laser source used, is suppressed. This way, smallest optical signals can be extracted from the signal measurement path that would otherwise be buried in the noise.

Spectral Range
190...1100 nm or 900...1700 nm

Gain
Adjustable Gain from 103 to 1011 V/W up to 500 KHz or fixed gain up to 2 GHz

Rise/Fall Time
18 ms to 180 ps

Applications
Spectroscopy, Fast Pulse and Transient Measurements, Optical Triggering, Optical Front-End for Oscilloscopes and A/D Converters, Fluorescence Measurements, Electrophoresis, Chromatography, Calibration of Optical Communication Systems and Time-Resolved Pulse
