HUMIDITY RANGE—
0 to 95% relative humidity, can withstand 100%
condensing humidity for short periods of time.
SPECTRAL SENSITIVITY RANGE—
UV radiation over the wavelength of 1850 to 2450
angstroms (solar blind).
CONE OF VISION—
The detector has a 90 degree cone of vision with the
highest sensitivity lying along its central axis. See
Figure X-3.
