| Definition | A submersible instrument designed to measure irradiance over the 4-pi photosynthetically active radiation (PAR) spectral range. It includes two hemispherical sensors to provide a spherical field of view and uses a logarithmic amplification to provide light measurements over several orders of magnitude. It uses a photodiode with enhanced blue/green sensitivity which, when used in conjunction with blue-tint glass, produces a quantum response that is flat to +/- 3 % over the range 450 to 700 nm, and 8 % at 400 nm The instrument has a depth rating of 500 m. | ||
