The USS-1200
and the USS-1200V Uniform Source Systems feature 12 inch diameter
Spectraflect integrating spheres designed to provide exceptionally
uniform luminance over the full 4 inch diameter sphere exit port.
Luminance output is variable from 2,300 to 9,000 foot-lamberts
on the USS-1200 and from zero to 9,000 foot-lamberts on the USS-120OV.
Uniformity is greater than 98%. Each system is calibrated to read
luminance in foot-lamberts. Calibration is traceable to National
Institute of Standards and Technology (NIST) standards.
The
USS-1200 Uniform Source System features a 12 inch diameter Spectraflect
integrating sphere outfitted with four internally mounted IHLS-100-30
30 watt Halogen Light Sources and four LPS-045-H Lamp Power
Supplies that provide regulated DC constant current control
to the light sources. The IHLS-100-30 Light Sources are mounted
equally spaced around the output port aperture. Each may be
separately activated to achieve four adjustable output levels.
Luminance output is variable from 2,300 to 9,000 foot-lamberts.
An SDA-050-P Silicon Detector Assembly monitors the luminance
at the exit port aperture. The system is operated through the
SC-5500 Integrating Sphere System Control, a sophisticated radiometer
that offers both an IEEE-488 bus and an RS-232C serial port
for optional computerization of the system.
The USS-1200V
Uniform Source System features both the VA-100-SC Motorized
Variable Attenuator and VAC-1000 Variable Attenuator Control
to provide the benefit of more precise control of low light
levels. The VAC-1000, combined with the SC-5500 Integrating
Sphere System Control and a personal computer, allow the user
to set the VA-100-SC to any of 256 linear steps. Three IHLS-100-30
30 watt Halogen Light Sources and one EHLS-100-75R 75 watt
externally mounted halogen light source provide input to the
integrating sphere. Three LPS-045-H Lamp Power Supplies and
one LPS-200H Lamp Power Supply provide DC regulated constant
current to the light sources. Luminance output is variable
from zero to 9,000 foot-lamberts. An SDA-050-P Silicon Detector
Assembly monitors the luminance at the exit port. Windows-based
software is provided with the USS-1200V Uniform Source System.
The Windows-based
software supplied with the USS-1200V consists of a single
screen that shows a slide control for adjustment of the variable
attenuators, and on/off control of the system's lamps.
The luminous
level of the exit port is continuously displayed on the computer
screen. The software may be operated by a mouse or the computer
keyboard and requires no further programming. Custom software
packages can be developed to allow the user, through feedback
loops, to program in special characteristics.
The
USC-PM is a point-by-point luminance measurement of the exit
port plane to determine the actual uniformity.
The
USC-SR is a spectral radiance measurement from 300 to 2400 nm
to determine the actual spectral radiance in W/cm2/sr/µm.
