Two new families of planar diffused ultraviolet photodiodes from
OSI Optoelectronics are now available from
AMS Technologies: the UV-EQ/EQC/EK and
the UV-DQ/DQC/DK series. The silicon is processed for enhanced responsivity over
200 to 400 nm and guaranteed sensitivity down to 190 nm. Both series are sensitive
down to 320 nm with suppressed response in the near-infrared region. Featuring metal
or ceramic packaging and a quartz or borosilicate window, the devices can be reverse-biased
for applications requiring lower capacitance, faster response or a wider dynamic
range. They are available in a hermetically sealed package at lower cost and are
suitable for spectrophotometers and analytical and medical instruments.
