Spectronics Corporation has unveiled the QUADRAN 365 and 365 S-Series — multi-LED, broad-beam UV-A (365 nm) inspection lamps. Both the 365 and 365 S-series feature four ultra-hi-flux UV-A LEDs for fluorescent inspection, plus a white light LED for flaw location. Their broad-beam configuration produces an extremely wide coverage area of up to 5 in. (13 cm) for the s-series and 6 in. (15 cm) for the standard 365, with a minimum UV-A intensity of 2,000 µW/cm² at 15 in. (38 cm). The white light LED’s high-intensity setting is 300 foot-candles (3,229 lux) and their low-intensity setting is 10 foot-candles (108 lux).
The QUADRAN 365 Series lamps are available in two models, 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 that feature a faceplate with integral black light filters covering the LEDs, which further reduce the emission of wavelengths longer than 400 nm.
The QUADRAN 365 S-Series lamps are available in two models, QDR-365S and QDR-365SBL. To address aerospace industry concerns, both units are “tuned” to a maximum UV-A intensity of 4,500 µW/cm² at 15 in. (38 cm). The QDR-365S comes with a standard faceplate and the QDR-365SBL comes with a faceplate containing integral black light filters that further reduce the emission of wavelengths longer than 400 nm. Both models have a high/low switch to control the white light LED output.
The lamps can be hand-held or used for in-line inspections.
