Opto Diode (Newbury Park, CA) a division of ITW, has announced the second in the AXUV series of multi-element photodiodes. The new 20-element AXUV20ELG features a 22-pin, dual in-line package with 100 percent internal quantum efficiency (QE). Bolometry, the measurement of minute amounts of radiant energy, is a key application for this highly sensitive photodiode. The device is also ideal for electron detection, providing EUV-UV and UV-VIS-NIR photon responsivity (measured in amperes per watt).
The AXUV20ELG includes an active area of 0.75 mm x 4.1 mm and a sensitive area of 3 mm² per element. The reverse breakdown voltage is typically 25 volts and the capacitance is 40 pF maximum (at 25°C, per element). With a rise time of 200 nsec and shunt resistance (per element) at a minimum 100 MOhms, Opto Diode’s new 20-element photodiode provides exceptionally stable response after exposure to high energy radiation.
