Triple wavelength pointing device

Abstract

This application discloses systems and methods of a laser device which could be used to aim firearms. The device includes a laser diode capable of emitting two or more different wavelengths of light to form a laser using a collimator, for example a single collimator or a compound collimator. In embodiments using a single collimator, the collimator can be repositioned at different distances from the laser diode to ensure proper positioning to create a laser beam for the particular wavelength of light emitted from the laser diode. In embodiments using a compound collimator, the collimator could have different collimating regions and be configured to rotate to cause the different collimating regions to receive light emitted from the laser diode such that different light wavelengths are properly collimated without needing to alter the distance from the collimator to the laser diode.
