The
USS-6500 Uniform Calibration Source features a 65 inch diameter
Spectraflect integrating sphere designed to provide exceptionally
uniform illuminance over a full 22 inch diameter sphere exit port.
Luminance output is variable from 500 to 10,000 foot-lamberts.
Uniformity is greater than 98%.
The USS-6500
includes twenty IHLS-DM-150, 150 watt halogen light sources which
can be selectively activated to achieve twenty distinct output
levels. Twenty 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,
however, 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/cm2/sr/µm.
