B 5.6 Carter-Scott Design Middleton SP02 Sunphotom eter
The Middleton SP02 Sunphotom eter is a sim ple low-cost instrum ent for the determ ination of the spectral
optical depth of the atm osphere. It consists of four precision spectro-pyrheliom eters axially aligned in
a sealed enclosure.
• Four narrow-bandwidth channels operate sim ultaneously
• Low- noise signal am plifiers with negligible drift
• External gain trim for each channel (via rear access ports)
• Tem perature output for therm al response correction
