~135 mA of output current. This will damage the output driver of the PDA10JT. CAUTION The PDA10JT 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. When using fiber adapters, make sure that the fiber ferrule does not crash into the detector. -
Page 5: Chapter 3 Description
The SM1-threaded mount can be easily integrated into our cage and lens tube systems. The PDA10JT 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, 50 - 60 Hz power supply. -
Page 6: Chapter 4 Setup
Figure 1 Electrical Connections Unpack the detector head. (Optional) Install a Thorlabs TR-series Ø1/2" diameter post (not included) into one of the 8-32 (M4 on –EC version) tapped holes located on the bottom and side of the head, and mount into a PH-series Post Holder (not included). - Page 7 Amplified MCT Detector Chapter 4: Setup Turn on the PDA10JT 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 PDA10JT 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.

Page 8: Chapter 5 Operation
(i.e. R LOAD signal level out of the PDA10JT 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 9: Bandwidth Filter Adjustment
The PDA10JT also includes an adjustable low pass filter with settings from 1.25 kHz to 160 kHz in 8 steps. This filter allows the user to optimize the PDA10JT 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. -
Page 10: Chapter 6 Maintenance
Chapter 6: Maintenance Chapter 6 Maintenance There are no serviceable parts in the PDA10JT detector or power supply. The housing may be cleaned by wiping with a soft damp cloth. The window of the detector should only be cleaned using isopropyl alcohol and optical grade wipes. -
Page 11: Chapter 7 Specifications
Operating Temperature 0 to 30 °C All measurements performed with a 50 Ω load unless stated otherwise. The PDA10JT 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. -

1.84 x 10 7.2. Detectivity Figure 3 PDA10JT Detectivity (D*) Gain with a 50 Ω load is one-half the hi-Z gain. NEP values measured using a 50 Ω load and a low-pass filter setting of 160 kHz; calculated at the detector’s peak responsivity wavelength. -
Page 13: Filter Bandwidth
Amplified MCT Detector Chapter 7: Specifications Detectivity (D*) is defined as is defined as: √ �� ∙ ∆�� ∗ �� ������ Where A is the area of the photosensitive region of the detector, Δf is the effective noise bandwidth, and NEP is the noise equivalent power. 7.3. -
