Examples of custom-built PMT setup for luminescence recordings. (A) Example of the light-tight box for PMT housing. Four HC135 photon-counting modules are located inside the light-tight box. The box is kept in an environmental chamber in which the temperature is set at 35.5°. A small fan with baffles is used for circulating the air inside the light-tight box and temperature inside of the box stays at 36.5°. (B) Example of the use of a light-tight incubator. Eight HC135 photon-counting modules are located inside the incubator. Black cardboard is used for the shielding of light, and black plastic sheet is placed between the inside glass door and the metal outside door to prevent light leaks.
