1 General Information
Thorlabs' PDAVJx Series of mid-IR (MIR) detectors combines the uncooled highly sensitive
photovoltaic mercury-cadmium-telluride (MCT) sensors of the VMLxT0 series with variable gain
ultra-low noise transimpedance amplifiers in a shielded aluminum housing. The PDAVJx detectors are DC coupled and have a frequency response from true DC to the respective cutoff
frequency. The gain can be adjusted with 8 steps over 30 dB (PDAVJ8 and PDAVJ10) or 42 dB
(PDAVJ5).
The PDAVJx Series for free-space beam setups is provided in different versions with varying
wavelength dependent sensitivity: the PDAVJ5 for 2.7 - 5.0 mm detection, the PDAVJ8 for 2.0 -
8.0 mm detection and the PDAVJ10 for 2.0 - 10.6 mm detection. A buffered output drives 50 W
loads up to 1.0 V with an NEP of 14 pW/Hz
210 pW/Hz
1/2
for PDAVJ10.
The sensors of the VMLxT0 series that are incorporated in the PDAVJx sensors differ in their
layers such that PDAVJ5 has a single layer, while PDAVJ8 and PDAVJ10 sensors have multiple layers. For that reason, the responsivities given for PDAVJ8 and PDAVJ10 are inseparable
from the sensor width.
The PDAVJx detector housing can be integrated in optical setups using convenient combithread mounting holes that are compatible with both imperial and metric mounting. Please see
the chapter Mounting for details.

The housing accommodates adapters and accessories from the Thorlabs’ SM05-threaded
(0.535"-40) series and the SM1-threaded (1.035"-40) series. This allows convenient mounting
of external optics, light filters, and apertures. For accessories, please visit our website or con-
tact Thorlabs.

A ±12 VDC power supply is included with each amplified photodetector. The appropriate input
voltage (100 VAC, 120 VAC, or 230 VAC) can be selected with a switch on the power sup-
4
ply.
The PDAVJx detectors can provide amplification of input powers up to 500 µW (PDAVJ10).
Detectors for amplification of higher input powers are available upon request.
Attention
Please find all safety information and warnings concerning this product in the chapter Safety
in the Appendix of the full manual.
1.1 Ordering Codes and Accessories
The following models of the PDAVJx Series and accessories are available:
Inspect the shipping container for damage.
If the shipping container seems to be damaged, keep it until you have inspected the contents
for completeness and tested the PDAVJx Series Detector mechanically and electrically.
Verify that you have received the following items within the package:
1. Amplified Adjustable-Gain MIR Photodetector
2. Metal Cover Cap, Protecting the Sensor
3. Power Supply (±12 V, 250 mA), Switchable 100 V, 120 V or 230 V Line Voltage, Including
Location Specific Power Adapters
4. Quick Reference Document
2.2 Preparation
Note
Prior to operation, please check if the selected line voltage range on the power supply matches
your local mains voltage.
Please follow these steps for preparation:
· Carefully unpack the unit and accessories. If any damage is evident, do not use the unit
and contact Thorlabs.
· Mount the unit on your optical table or application. The unit has two combi thread mounting holes, each compatible with both imperial 8-32 and metric M4 screws.
· Remove the metal cover cap that protects the optical input.
· If necessary, mount external optics, filters, or apertures.
· Adjust the power supply to accommodate your local mains voltage (100 VAC, 120 VAC, or
230 VAC).
· Plug the power connector cable into the power supply connection socket on the PDAVJx.
· Plug the power supply into a 50-60 Hz, 100 VAC, 120 VAC, or 230 VAC outlet.
· Turn the power supply on.
· Connect the output BNC connector to your data acquisition device using a coaxial cable.
Please note that a 50 W impedance device should be used for best RF performance.

Note
If you want to use your own power supply, contact Thorlabs for an appropriate power connector
cable.
The safety of any system incorporating the equipment is the responsibility of the assembler of
the system.
All statements regarding safety of operation and technical data in this instruction manual will
only apply when the unit is operated under the conditions it was designed for.
The PDAVJx must not be operated in explosion endangered environments!
Do not open the housing. There are no user-serviceable parts inside!
This precision device is only serviceable if returned and properly packed into the complete ori-
ginal packaging including the plastic foam sleeves. If necessary, ask for replacement packaging. Refer servicing to qualified personnel!
Changes to this device cannot be made nor may components not supplied by Thorlabs be used
without written consent from Thorlabs.
Attention
Prior to applying power to the PDAVJx, make sure that the protective conductor of the 3 conductor mains power cord is correctly connected to the protective earth ground contact of the
socket outlet! Improper grounding can cause electric shock resulting in damage to your health
or even death!
Ensure that the line voltage setting of the fuse holder at the power supply agrees with your local
supply and that the corresponding fuses are inserted. If not, please change the line voltage setting.
To avoid risk of fire, only the appropriate fuses for the corresponding line voltage must be used.
All modules must only be operated with properly shielded connection cables.
Users that change or modify the product described in this manual in a way not expressly ap-
proved by Thorlabs (party responsible for compliance) could void the user’s authority to operate
