Using a multichannel quartz optical-fiber system calibrated with a standard tungsten strip lamp, the radial profiles of the visible bremsstrahlung radiation power in the HL-1 tokamak were measured.

Optical performance was measured under the irradiation of the CHF-XM35-500W xenon lamp with a parallel light source system.

A sphere large-power short arc xenon lamp is used as the light source of this equipment. Deep ellipsoidal optical focusing system, cooling system and power source are designed reasonably.
