Mercury Short Arc High-Pressure Lamps
Ushio’s super high-pressure UV mercury lamps of the USH series have been developed to effectively utilize three ultraviolet wavelengths (436, 405 and 365 nm) as high-intensity light sources with stable irradiance and long life.
Since the lamp's arc size is nearly that of a point light source, the light can be readily converged and diffused by the optical system, and uniform illuminance distribution is easily obtained. Mercury short arc lamps are the preferred choice in the semiconductor industry as well as the PCB industry.
Our mercury short-arc high wattage lamps function in the same way as their low wattage counterparts. These high wattage lamps range from 1,000 W to 12,000 W.
