UV-A LED Lamp Eases NDT Inspection
April 3, 2014
Suiting a wide variety of NDT inspection applications, the QUADRAN 365 Series multi-LED, dual-intensity, broad-beam UV-A (365 nm) inspection lamps feature four ultra-hi-flux UV-A LEDs for fluorescent inspection plus a white light LED for flaw location. A broad-beam configuration produces a coverage area up to 6 in. (15 cm) with a minimum UV-A intensity of 2,000 µW/cm² at 15 in. (38 cm). Two models are available, the QDR-365 and QDR-365BL, each with high-intensity and standard-intensity settings. The high setting produces a nominal steady-state UV-A intensity of up to 8,000 µW/cm² and the standard setting produces a nominal steady-state intensity of 4,500 µW/cm², both measured at 15 in. (38 cm). Versions are also available with black light filters to reduce the emission of wavelengths longer than 400 nm. The white light LED’s high-intensity setting is 300 foot-candles (3,229 lux) and its low-intensity setting is 10 foot-candles (108 lux).
