The service cabinet houses a DC power supply, high voltage ignitor and microcomputer-based controller. Lamp ignition is accomplished by impressing high voltage from an internal ignitor. The positions of the optical surfaces are designed using a Vortek proprietary optical analysis program to accurately produce a solar beam of the specified uniformity and irradiance. The Reflector is rigidly mounted to the Lamphead. Interior sections of the Reflector are machined from aluminum alloy and internally water cooled.
Optical surfaces are polished and protected with damage-resistant reflective coatings.
Exterior Reflector sections are constructed of air-cooled glass mirrors.
