lamp standard or in absence of such standards, the
appropriate national standards or manufacturer’s
recommendations.

Note 1: The area of 300 nm to 700 nm covers parts of the UV-B-radiation, the total UV-A-radiation and the
major part of the visible radiation; the resulting danger is generally termed as danger through “blue-light”.
However, blue-light in a strict sense only covers the area of ca. 400 nm to 490 nm.
Note 2: With constantly fixation of very small sources with an angular expansion of less than 11 mrad, LB
can be converted into EB. Normally this is only the case with ophthalmic instruments or an eye-stabilization
ଵ଴଴
during an anaesthesia. The maximum “rigidity-time” is calculated by the following formular: tmax =
