Visual inspection with LED flashlight unspecified why?
The instructions for visual inspection of a maintenance task specified not to use an LED flashlight why? Does the white color of light at the expense of a visual inspection, are they too Bright does the frequency of blocking the light of the detection of cracks or shadows? I do not think Robert is right, because the procedure, if the cracks States were found or suspected to carry out an inspection penetrant.
nm = nanometers. White LEDs are made up of three colors Primary (Red – 650 nm, green – 575 nm and Blue – 475 nm). The lights are combined to make white. LEDs emit light in a wavelength very close. Surfaces that reflect light outside the range 450-675 nm does not reflect all the light when using a LED. In addition, all surfaces that reflect light in the range 525 nm would also not be visible. Incandescent light emits light in a spectrum very wide across the spectrum of visible light. Visible light is in the 380 to 770 nm. Thus, a White Led would not reflect light between 380 nm – 425 nm and 675 nm – 770 nm along with a narrow band near 525 nm.
