Page 4: Chapter 2 Description
The SM1-threaded mount can be easily integrated into our cage and lens tube systems. The PDA10DT(-EC) has two 8-32 (M4) tapped holes for mounting the detector on a Ø1/2" optical post in one of two perpendicular directions. The detector includes a 100 - 240 V, 47 - 63 Hz power supply. -
Page 5: Chapter 3 Setup
Attach a 50 Ω BNC cable 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’ T4119 BNC in-line terminator) for maximum performance. Connect the remaining end to a measurement device such as an oscilloscope or high-speed DAQ card. - Page 6 Amplified InGaAs Detector Chapter 3: Setup Turn on the PDA10DT using the power switch located on the top side of the detector. Install any desired filters, optics, adapters, or fiber adapters to the input aperture. CAUTION The PDA10DT was designed to allow maximum accessibility to the photodetector by having the front surface of the diode flush with the outside of the PDA housing.

> 5 kΩ) and 5 V for 50 Ω loads. Adjust the gain so that the measured signal level out of the PDA10DT is below 10 V (5 V for a 50 Ω load) to avoid saturation. If necessary, use external neutral density filters to reduce the input light level. The BNC output signal is buffered with an amplifier capable of driving 50 Ω... -
Page 8: Bandwidth Filter Adjustment
The PDA10DT also includes an adjustable low-pass filter with settings from 500 Hz to 1 MHz in 8 steps. This filter allows the user to optimize the PDA10DT to operate at the lowest amount of high-frequency optical and electrical noise. The filter is adjusted by rotating the filter control knob, located on the side of the unit. -

0 V (20 dB - 70 dB) All measurements performed with a 50 Ω load unless stated otherwise. The PDA10DT has a 50 Ω series terminator resistor (i.e., in series with amplifier output). This forms a voltage divider with any load impedance (e.g., 50 Ω... - Page 11 Amplified InGaAs Detector Chapter 7: Specifications General Specifications Detector Extended InGaAs PIN Active Area 0.8 mm (Ø1.0 mm) Surface Depth 0.08" (2.0 mm) Output Weight (Detector/Power Supply) 0.42 lbs / 0.82 lbs (191 g / 372 g) Power Supply 30 W 100 - 240 VAC, 47 –...
