The R488 is an end-view phototube designed to be particularly sensitive to UV light. This tube is packaged in a small cylindrical envelope with a flat front window and a pair of flying leads. Unlike many other phototubes, which have an argon fill gas, the R488 is a hard vacuum tube. In operation, photons striking the cathode in the center of the tube would release a spray of electrons that would be collected by the mesh-shaped anode visible through the tube's front window.
