The ONT-365 On-Trak nondestructive testing (NDT) and inspection system from Spectronics is an overhead track light-style modular system with powerful UV-A and white light LEDs attached to a mountable platform. It is suited for use in NDT inspection booths and for preinspections and screening applications requiring maximum uniformity of coverage over a large area. The system features four broad-beam lamp heads, each of which has three ultrahigh-flux UV-A (365-nm) LEDs for NDT inspection and one white light LED for general illumination. Inspectors can move the lamp heads anywhere along the tracks to customize beam patterns for specific needs. Lamp heads can be added for increased area coverage. The light sources produce a nominal steady-state UV-A intensity of 9000 µW/cm² at 15 in.
