The invention relates to a manual lamp, especially for optical crack testing according to the magnetic powder testing and dye penetration method. Said manual lamp comprises at least one LED having an emission wavelength located in the UVA range as an illuminating means.
摘要:
Processes and devices for the photothermal inspection of a test body. Lighting radiation with short lighting times is applied to a test body and at least one measurement value of the emission curve during or after a short lighting time is sensed. The diffusion and/or effusion capacity of a test body coating layer, for example, can be determined by computer units on the basis of the measurement value(s), even when the thickness of the coating layer is unknown, because the measurement values are detected during or shortly after irradiation and the coating layer thickness plays only an insignificant role in the course of the emission curve in this range.
