B 5.6 Carter-Scott Design Middleton SP02 Sunphotometer

The Middleton SP02 Sunphotometer is a simple low-cost instrument for the determination of the spectral

optical depth of the atm osphere. It consists of four precision spectro-pyrheliometers axially aligned in

a sealed enclosure.

• Four narrow-bandwidth channels operate simultaneously

• Low- noise signal amplifiers with negligible drift

• External gain trim for each channel (via rear access ports)

• Temperature output for thermal response correction
