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.
