Spectral Response
Temperature Response
Mean temperature response of eight SQ series
quantum sensors (
errors bars represent two
standard deviations above and below mean
).
Temperature response measurements were
made at 10 C intervals across a temperature
range of approximately -10 to 40 C in a
temperature controlled chamber under a fixed,
broad spectrum, electric lamp. At each
temperature set point, a spectroradiometer was
used to measure light intensity from the lamp
and all quantum sensors were compared to the
spectroradiometer. The spectroradiometer was
mounted external to the temperature control
chamber and remained at room temperature
during the experiment.
Mean spectral response of six SQ series quantum
sensors (
error bars represent two standard
deviations above and below mean
) compared to
PPFD weighting function. Spectral response
measurements were made at 10 nm increments
across a wavelength range of 300 to 800 nm in a
monochromator with an attached electric light
source. Measured spectral data from each
quantum sensor were normalized by the
measured spectral response of the
monochromator/electric light combination,
which was measured with a spectroradiometer.
