Abstract
Light passing through an exposure controlling device is made incident on a body which is photosensitive both within and outside a visible range. The method is so designed as to limit the spectroscopic radiation intensity both in a short and long wavelength region within the visible range and that the spectroscopic radiation intensity has one or more peaks outside the visible range.
Claims3
A method of controlling incident light on a body which is photosensitive not only within a visible range of light but also outside said visible range, said method comprising the steps of
- limiting the spectroscopic radiation intensity of said incident light both in a short wavelength region and in a long wavelength region within said visible range, and
- providing one or more peaks in the spectroscopic radiation intensity of said incident light with one or more peaks outside said visible range.
