Laser is a kind of light radiation with strong directionality and concentrated energy, which is very beneficial for realizing the high precision, convenience and automation of the measurement process. Taking advantage of the characteristics of laser, this product can be used for: It can be used for high-precision angular coordinate measurement and directional alignment measurement occasions, such as: manufacturing of large ships; displacement measurement of small and medium-sized dams; Deformation measurement of parts; port and bridge engineering; laying of large pipelines and pipelines; tunnel and tunnel engineering; high-rise buildings, large towers; aircraft rack installation; vertical line measurement in the direction of the zenith;
This product is a semiconductor laser introduced into the J2 optical theodolite, which is launched through a telescope. The laser beam and the collimation axis of the telescope are kept coaxial and co-focal. Therefore, in addition to all the functions of an optical theodolite, this product also provides a visible laser beam, which is very convenient for engineering construction. Because the semiconductor laser transmitter has the advantages of long service life and low power consumption compared with the gas generator, this product can work for one working day using two AA batteries. This product is also equipped with a double curved eyepiece, which is convenient for users to observe the zenith direction. If the laser is not used, the instrument can still be used as a general 2" optical theodolite.
