Fundamentals of Optical Physics
In the electromagnetic spectrum the wavelengths covered by optical radiation range from 1 nm to 1 mm. This wavelength region includes not only the visible part of the electromagnetic spectrum, but also the ultraviolet (UV) — up to the soft ionizing X-ray domain — and the infrared (IR) — up to the microwave domain. The region from 1 nm to 190 nm (vacuum UV) is completely absorbed in air and consequently has no direct biological effect.
