Hamamatsu Camera

This service controls a Hamamatsu camera. It is a wrapper around the DCAM SDK, which is distributed on the manufacturer website together with their Python API dcam: https://www.hamamatsu.com/eu/en/product/cameras/software/driver-software.html

The service requires the definition of an environment variable CATKIT_DCAM_SDK_PATH that points to the python directory within the DCAM SDK installation.

The service has been successfully tested with the following camera models:

• Hamamatsu ORCA-Quest C15550-20UP

• Hamamatsu ORCA-Quest 2 C15550-22UP
