Thus it was decided to include reference measurement techniques for lamps and lamp systems in this standard. The evaluation and control of optical radiation hazards from lamps and lamp systems is a far more complicated subject than similar tasks for a single-wavelength laser system.

Finally, there are well known optical radiation hazards associated with some lamps and lamp systems. To evaluate a broad-band optical source, such as an arc lamp, an incandescent lamp, a fluorescent lamp, an array of lamps or a lamp system, it is first necessary to determine the spectral distribution of optical radiation emitted from the source at the point or cif of nearest human access.

The required radiometric measurements are quite involved, for s090 do not deal with the simple optics of a point source, but rather with an extended source that may or may not be altered by diffusers or projection optics.

Also the wavelength distribution of the lamp may be altered by ancillary optical elements, diffusers, lenses, and the like, as well as variations in operating conditions. Thus it was decided to include reference measurement techniques for lamps and lamp systems coe this standard.

Lamps were developed and produced in large quantities and became commonplace in an era when industry-wide safety standards were not the norm. The performance of the necessary measurements is normally not an easy task without sophisticated instruments. The purpose of this standard is to provide a standardized technique for evaluation of potential radiation hazards that may be vie with various lamps and lamp systems.
