ABSTRACT:
A laser system for surveying, which comprises a laser light source unit, an optical system for irradiating a laser beam from the laser light source unit toward a given direction, whereby said laser light source unit is at least thermally isolated from the optical system, and the laser beam from the laser light source unit is guided toward the optical system by an optical fiber. Because the laser light source unit, or at least a heat generating portion of the light source unit is isolated from the optical system, no influence of heat from the laster light source unit is exerted on the optical system, and it is possible to prevent decrease of accuracy due to heat and to maintain the laser system for surveying in a condition to provide measurement at high accuracy.
