The H10493 series photosensor modules incorporate a 28 mm (1-1/8") diameter head-on photomultiplier tube, a high voltage power supply, and a low noise amplifier. Since it has a wide photosensitive area of 25 mm diameter, light can be collected efficiently. Amplifiers are available with a current-to-voltage conversion factor of 1 V/μA or 0.1 V/μA and a frequency bandwidth of DC to 20 kHz, DC to 200 kHz or DC to 8 MHz. Photomultiplier tubes with different spectral response characteristics are provided for measurement in the visible range or UV to near IR range.
