Spectral Response
Temperature Response
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.
Mean spectral response measurements of
six replicate Apogee SQ-100 (original) and
SQ-500 (full-spectrum) series quantum
sensor. 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.
