The USS-2000
and the USS-2000V Uniform Calibration Source Systems each feature
20 inch diameter Spectraflect integrating spheres designed to
provide exceptionally uniform luminance over a full 8 inch diameter
sphere exit port. Luminance output is variable from 1050 to 9000
foot-lamberts on the USS-2000, and zero to 4000 foot-lamberts
on the USS-2000V. Uniformity is greater than 98%. Each system
is calibrated to read luminance in foot-lamberts. Calibration
is traceable to the National Institute of Standards and Technology
(NIST) standards.
The USS-2000 Uniform Calibration Source features
a 20 inch diameter Spectraflect integrating sphere equipped
with two IHLS-DM-045, 45 watt halogen light sources and two
IHLS-DM-150, 150 watt halogen light sources which provide diffuse
input to the sphere. Two LPS-045-H Lamp Power Supplies and two
LPS-200-H Lamp Power Supplies provide regulated DC constant
current to the light sources. The light sources can be selectively
activated to achieve eight distinct output levels. Luminance
output is variable from 1050 to 9000 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-2000V Uniform Calibration Source features a both the VA-100-SC
motorized Variable Attenuator and the VAC-1000 Variable Attenuator
Control to provide 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-DM-045, 45 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-200-H Lamp Power
Supply provide DC regulated constant current to the light sources.
Each light source may be activated separately to achieve many
adjustable output levels. Luminance output is variable from zero
to 4000 foot-lamberts. An SDA-050-P Silicon Detector Assembly
monitors the luminance at the exit port. Windows-based software
is provided with the USS-2000V Uniform Source System.
The
Windows-based software supplied with the USS-2000V Uniform Calibration
Source System consists of a single screen that shows a slide control
for adjustment of the variable attenuators, and an on/off control
of the system's lamps. The luminance of the exit port is continuously
displayed on the 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.
