b) Blue Light Transilluminators
No special UV protection is required for blue light transilluminators. The tubes used in the blue
light transilluminator have an emission wavelength of 400 - 480 nm. These tubes are also used,
for example, to check paper money in banks and industrial facilities.
The health hazard caused by these tubes is low. The UV-A intensities are reduced by 2 filter
glasses.

No UV protection is needed for white light transilluminators. Nevertheless, make sure to wear
standard safety glasses due to the high intensity of the light source. These safety glasses en-
sure that bright, intense light intensity will not be harmful to the eye of the beholder. All safety
glasses that reduce the light intensity by approx. 50% can be used.
Every transilluminator may be operated only by persons who have been trained and instructed
accordingly and who possess the appropriate authorization. These persons must be familiar
