The
USS-4000 Uniform Calibration Source features a 40 inch diameter
Spectraflect integrating sphere designed to provide exceptionally
uniform illuminance over a full 14 inch diameter sphere exit port.
Luminance output is variable from 1000 to 10,000 foot-lamberts.
Uniformity is greater than 98%.
The USS-4000
includes ten IHLS-DM-150, 150 watt halogen light sources which
can be selectively activated to achieve ten distinct output levels.
Ten LPS-200-H Power Supplies provide regulated DC constant current
to operate the light sources. An SDA-050-P Silicon Detector Assembly
monitors the luminance at the sphere 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.
System
calibrations are performed in the Labsphere Optical Calibration
Laboratory with standards traceable to national laboratories.
The system is calibrated to read luminance in foot-lamberts.
Customers may specify optional calibrations to accommodate specific
needs. Available calibrations include luminance, radiance, actual
uniformity and spectral energy distribution.
The
basic software provided with Labsphere uniform calibration source
systems consists of a single screen which allows the user to
control on/off operation of light sources to achieve desired
output levels at the sphere exit port. Custom software packages
can be developed to allow the user to program special characteristics.
Please discuss your specific software requirements with a member
of our Technical Sales Department.
The
USC-PM is a point-by-point luminance measurement of the exit
port plane to determine actual uniformity.
The
USC-SR is a spectral radiance measurement from 300 to 2400 nm
to determine the actual spectral radiance output in mW/cm(2)/sr/um.
