ABSTRACT:
In a luminous dot sighting instrument: dots of different color are produced using different mirror coatings that differentially reflect different wavelengths of light from a single diode or several diodes of the same color, or from different color diodes; dots at different positions on the image of the target view of the instrument are obtained by spacing apart mirror coatings for reflecting light from a single diode, or by by spacing apart several diodes, or a combination of both; dots of different brightness on the image of the target view are obtained by spacing apart mirror coatings for reflecting light from a single diode so that light reflects from the near side and from the far side of the lens and so the far side reflected light is less bright on the image than the near side reflected light; and some embodiments incorporate more than one or all of these features.
