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 with a monochromator
and 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 -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.
