Specialized Black Filter Lens
99% stray light filtered by specialized UV filter black lens， Which makes fluorescent inspection easier, faster and more reliable.
Since tail emission is visible as deep violet light, adding the UV-A pass filter eliminates the glare and makes the background of
the part surface darker. This increases contrast between fluorescent indications and the darkened part surface when using
fluorescent magnetic particle or penetrant techniques.
