Spectral Response
Temperature Response
Mean spectral response measurements of
six replicate Apogee SQ-100 (original) and
SQ-500 (full-spectrum) series quantum
sensors. 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.
Mean temperature response of ten SQ-500
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 -20 to 50 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.
