The 1800-02 and quartz halogen lamp are traceable to the National Institute of Standards and
Technology (NIST).
Spectral Response:
Temperature response:
Mean spectral response of six SQ series
error bars represent two
quantum sensors (
standard deviations above and below
mean
) compared to PPF 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.
Mean temperature response of eight SQ
series quantum sensors (
represent two standard deviations
above and below mean
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.
