1.1.5.1 Sensors
Features
20C-SH
ֺ
ֺ Conduction cooled
ֺ
ֺ Spectrally flat
ֺ
ֺ “A” version gives analog voltage calibrated to power
ֺ
ֺ “UA” version can give analog voltage output or
digital RS232 output and can measure power or
energy. Can also have multiple switchable ranges
and/or multiple switchable wavelengths
ֺ
ֺ "UAU" version is similar to the UA version but operates via the
USB terminal of the PC
These specifications refer to standard OEM sensors, and are to be understood as generic, describing sensor families. Ophir will be happy to
help you with a specific solution for your particular application.
