Page 4: Chapter 2 Description
Chapter 2: Description Chapter 2 Description The PDA10CF(-EC) is an amplified, InGaAs detector designed for detection of light signals ranging from 800 to 1700 nm. A buffered output drives 50 Ω load impedances up to 5 V. The PDA10CF(-EC) housing includes a removable threaded coupler (SM1T1) and retainer ring (SM1RR) that is compatible with any number of Thorlabs 1”... -
Page 5: Chapter 3 Setup
Attach a 50 Ω coax cable (i.e. RG-58U) to the output of the PDA. When running cable lengths longer than 12" we recommend terminating the opposite end of the coax with a 50 Ω resistor (Thorlabs p/n T4119) for maximum performance. Connect the remaining end to a measurement device such as an oscilloscope or high speed DAQ card. -

Chapter 4 Operation 4.1. Theory of Operation Thorlabs PDA series are ideal for measuring both pulsed and CW light sources. The PDA10CF(-EC) includes a reverse-biased PIN photo diode, mated to a fixed gain transimpedance amplifier, and packaged in a rugged housing. -
Page 7: Dark Current
InGaAs Amplified Detector Chapter 4: Operation 4.3. Dark Current Dark current is leakage current which flows when a bias voltage is applied to a photodiode. The PDA with Transimpedance Amplifier does control the dark current flowing out. Looking at the figure above, it can be noted that Point B is held at ground and the amplifier will try to hold point A to “Virtual Ground”. -

> 5 kΩ) and 5 V for 50 Ω loads. Adjust the gain so that the measured Load signal level out of the PDA10CF(-EC) is below 10 volts (5 volts with a 50 Ω load) to avoid saturation. For low terminating resistors, <5 kΩ or 1% error, an additional factor needs to be considered. -

InGaAs Amplified Detector Chapter 5: Troubleshooting Chapter 5 Troubleshooting Problem Suggested Solutions Verify that the power is switched on and all connections are secure. Verify the proper terminating resistor is installed if using a Voltage measurement device. There is no signal response. Verify that the optical signal wavelength is within the specified wavelength range. -
