Product Description

Approved American National StandardThis document describes the procedures to be followed and the precautions to be observed in performing uniform and reproducible measurements of the electrical and ultraviolet optical radiation characteristics of far UV-C excimer sources predominantly emitting at a peak wavelength within the far UV-C range (200 nm to 230 nm). The wavelength range for the purposes of this document is 200 nm to 300 nm.
