1L20 -
one dimensional PSD
The SiTek 1L20 PSD functions accor-
ding to the Lateral Effect-Photodiode prin-
ciple. It is an analogue device and therefore
displays excellent position resolution. The
resolution is determined by the system sig-
nal-to noise ratio.
The 1L20 is operated in the biased mode.
Typical applications include: distance and
height measurement, alignment, position
and motion measurements and vibration
studies.
Special UV- or YAG-enhanced and
Nuclear versions are available.
