SPDMHx Series 3 Operation
Rear View
The connectors on the back are labeled in the image of an SPDMH2 single photon detector.
The rear sides the SPDMHx Series models SPDMH2, SPDMH2F, SPDMH3, and SPDMH3F
look identical.
3.2 Mounting
The SPDMHx Series detectors can be integrated in an optical setup from the front side and
mounted on the base plate .
Front Side Integration
1. All models of the SPDMHx Series provide two mounting holes on the front side of the unit (8-
32 UNC threads, depth 8 mm). These can be used for mounting or integration in optical sys-
tems.
2. The SPDMH2 and SPDMH3 free space detectors additionally feature an internal SM1
thread, compatible with a variety of Thorlabs offers Optical Component Threading Adapters .
Note Please take the weight of the detector into account when this mounting style is used!
Base Plate Mounting
The base plate of the SPDMHx Series detector can be fastened on a bread board using the
CL4 table clamps. Alternatively, the detectors provide 6 mounting holes (3 holes each side) with
a diameter of 3.9 mm.
The base plate can be mounted using 6-32 screws.
For controlled positioning of the SPDMHx Series device, we recommend the following:
1. Mount the SPDMHx Series detector on a Thorlabs BA4 mounting base.
2. Subsequently, mount the BA4 mounting base on a suitable 3-Axis translation stage or other
means of positioning mechanics. This is highly recommended for precise positioning of the
free space detectors.
Attention
In order to avoid damage to the module, heat management must be provided by placing or
mounting the module onto a suitable heat sink, e.g. an optical table.
Attention
Before powering up the module it is strongly advised to make sure that no light reaches the
sensor.
