Abstract

Techniques disclosed herein provide for substantially uniform steering of multiple laser beams of a laser rangefinder having different wavelengths, such as a rangefinder laser beam and a visible laser beam. This can allow a user of the laser rangefinder to use the visible laser beam to bore sight the range-finding laser beam to a weapon onto which the laser rangefinder is mounted. The uniform steering of the multiple laser beams can be done through the utilization of a Risley prism assembly with one or more Risley prisms having a center portion through which one laser beam travels and at least one annulus through which a second laser beam travels.
