Latest Developments

The PDM04-9111-USB is incorporating a photomultiplier, HV power supply and signal processing electronics in an easy-to-use, compact rectangular, light-tight assembly.

The PDM03-9107-USB is incorporating a photomultiplier, HV power supply and signal processing electronics in an easy-to-use, rectangular, light-tight assembly.

The PDM02-9111-TTL is a compact, wide bandwith, rectangular format photon detection module with TTL output and 5V operation.

Over light detection flag is a high/low output that indicates to the user before the photomultiplier reaches saturation. The trigger point is set to approximately 25MHz, uncorrected count rate. When the output count rate of the photodetector module is above 25MHz, the over light detection flag is high (4V) and when the output count rate is below 25MHz, the over light detection flag is low.

Software for use with all ET Enterprises LTD PhotoDetector USB modules
