摘要
A system for providing variable wavelength intensity attenuation to said focused beams by application of an aperture-like element that comprises at least two regions of “filter” material, or comprises different materials graded into one another, which different materials that have different responses to different wavelengths, wherein said system is applied to reduce differences in wavelength intensity levels when applied in collimated portions of a beam as a Spectral Angle Adjustor (SAA) or to preserve information in a beam while changing said beam effective diameter as a Spectral Aperture Stop (SAS); or to affect a Spectral Field Stop (SFS) that controls source image size when applied at a convergent/divergent beam focal point as a Spectrally Varying Aperture, (SVA) the end result depending on where in a beam it is applied.
