Overview
The vacuum photodiode is a sealed vacuum tube with a much faster response than solid state photodiodes.
Vacuum Photodiodes do not contain the MicroChannel Plate electron multipliers used in our Photomultiplier Tubes, resulting in unity gain. A benefit of this is the vacuum photodiode’s large dynamic range, enabling measurement of extremely high light signals without degradation.
