The USS-1200V-LL Uniform Source System is specifically designed to provide spectral irradiance levels comparable to those of an m=0 star in the UV, VIS, and IR. Irradiance is variable over more than eight decades.
The USS-1200V-LL includes a satellite sphere illuminator with an external halogen light source and a motorized variable attenuator to provide precise control of illumination levels.
Features:

• Simulate stellar radiance
• Variable radiance levels Uniformity <98%
• 12 inch integrating sphere
• 4 inch diameter exit port
• Dual-band monitoring
• Source filter wheel
• Calibration
• Irradiance responsivity
• Spectral radiance and irrandiance

Aplications:

• Calibrate and test UV/VIS/NIR sensors
