licor_sensors
A character vector of names of members of the collection of spectra.
In the LI-190SA and LI-190 PAR quantum sensor (PAR = photosynthetically active radiation) colored glass filters are used to tailor the silicon photodiode response to the desired quantum response. They have the same spectral response.
The type of filter used in the LI-190R PAR quantum sensor is not described, but improves the spectral response compared to the LI-190.
The LI-200SA features a silicon photovoltaic detector. This is not a true 'pyranometer' and should be used only in sunlight, and calibrated in sunlight.
The LI-210SA Photometric Sensor utilizes a filtered silicon photodiode to provide a spectral response that matches the CIE curve within ± 5 light sources.
The LI-210R Photometric Sensor utilizes a filtered silicon photodiode to provide a spectral response that matches the CIE curve.
