General Description
The epc3xx family products are high-sensitive photo diodes for
light-barrier, light-curtain, and the like applications. These photo
diodes are designed to be used in a reverse-bias mode.
This device allows the design of short to long range light barriers
from a few millimeters up to tens of meters.
Using chips from the epc3xx product line, linear or two dimen-
sional arrays can be formed for any application, be it triangulation,
spot location, angle measurement, rotary encoders, or similar.
Also, spectral sensitive detectors can easily be designed by
applying color filters in front of the photo diodes.
Also, other mechanical dimensions are available upon request. It
is be possible to manufacture photo diodes of up to 15x15 mm or
even bigger. Such a 15x15 mm device then would contain 450
individual photo diodes, each of them individually accessible. All
diodes feature a very high quantum efficiency of 90% in the near
IR range, a reverse breakdown voltage of up to 30 Volts and a
response time down to less than 100ns. All devices are available
upon request with optical bandpass filters.
