The new wavelength calibration coefficients are now loaded onto the EEPROM memory chip on
the Flame.
Irradiance Calibrations
Irradiance calibrations and relative irradiance calibrations are about quantifying the spectra, by
translating the signal (incident number of photons) to a calibration. This can be either absolute
(an atomic emission light source of known output power) or relative (corrected for instrument
response function but not absolute units). It can be considered a measurement technique and
is used widely in remote sensing, light metrology and anywhere where you wish to characterize
the incident light source. Irradiance calibrations are not required for many techniques because
these measure the relative signal changes with respect to the sample and not the light source.

OceanView has wizards that will step you through absolute irradiance and relative calibrations
and more information on these is located in the OceanView manual (see Product-Related
Documentation ).
