Spectral selectivity ± 2%

percentage deviation of the

product of spectral absorptance

and spectral transmittance

from the corresponding mean

within 0.35 :m and 1.5 :m

Temperature response ± 1%

percentage deviation due to

change in ambient temperature

within an interval of -20 to +50 °C,

relative to 20 °C.

Tilt response 0.25%

percentage deviation from the

responsivity at 00 tilt (horizontal)

due to change in tilt from 0° to 90°
