Abstract
A spectral color generator is used in an optical sight for use as a gun sight, surveying instrument, or the like, with means for projecting light from the generator in the form of an illuminated reticle into the line of sight. The illumination from the generator is variable in color and intensity for maximum visibility against a variety of backgrounds, and means are provided for precise alignment, adjustment for elevation and windage and for levelling. In its basic form, the sight has long eye relief but is readily adaptable for use with telescopic attachments. The spectral color generator is also illustrated in an operational monitoring system responsive to sensing devices for monitoring a plurality of parameters including opacity and pressure.
