Super-Powerful UV Lamps Reveal Microscopic Flaws

Better Roads Staff | April 6, 2010

Westbury, New York—The MAXIMA™ ML-3500 Series ultraviolet lamps use advanced micro discharge light (MDL) technology, plus a unique filter and bulb/reflector, to deliver up to 10 times the UV-A (365nm) output of conventional HID inspection lamps. With these lamps, NDT inspectors can see the smallest surface defects, hydrocarbon contamination and other flaws that escape less powerful lamps. 

The ML-3500S model features a spot bulb and has a nominal steady-state UV-A intensity of 50,000 µWcm² at 15 inches (38cm). The ML-3500D spot with diffusing filter has a nominal steady-state UV-A intensity of 14,000 µWcm² at 15 inches. The ML-3500FL features a flood bulb that delivers a nominal steady-state intensity of 4,500 µW/cm² at 15 inches. All bulbs feature a rated life of 2,000 hours. An instant on/off/restrike eliminates lamp warm-up and reduces inspection time. The lamps produce virtually zero emission of hazardous UV-B and emit minimum visible light.

MAXIMA Series lamps are available in 120V, 230V, 240V and 100V AC versions as well as battery-operated versions that include a 12-volt, 7 amp/hr rechargeable battery, which will operate the lamp for two full hours. A battery recharger and carrying case are included.
