[0002] The laser collimator is a basic reference tool in the laser system. For the convenience of use, there are often two focal planes, one is the transmitting focal plane, and the other is the receiving focal plane. The two focal planes are conjugate and located in the collimator. The real focal plane is the basic requirement for its use. How to adjust the two focal planes to their conjugate positions is a key problem that needs to be solved when the instrument is installed. The usual method uses the joint adjustment of the focal plane and the light pipe, which takes a long time to adjust. Inconvenient to adjust and poor repeatability

The invention discloses a laser collimator double-focal-plane conjugation adjustment method and adjustment apparatus. The adjustment apparatus comprises a first point source, a second point source, a cross reticule, a light splitting prism, a first microscope, a second microscope and a third microscope, wherein the light splitting prism is a 45-degree light splitting prism and has a first focal plane and a second focal plane; the first point source is arranged on the first focal plane, the first focal plane and the first microscope are respectively disposed at the two sides of the light splitting prism, the second microscope and the third microscope are respectively disposed at the two sides of the light splitting prism, and a connecting line between the second microscope and the third microscope is vertical to the connecting line between the first point source and the first microscope; the second focal plane is disposed between the third microscope and the light splitting prism; the second pint source is arranged on the object surface of the second microscope; and the cross reticule is placed on the second focal plane. The adjustment apparatus provided by the invention employs conjugated double focal planes so as to conveniently determine a laser collimator focal plane.
Description
technical field [0001] The invention relates to a conjugate adjustment method and an adjustment device of the bifocal plane of a laser collimator. Background technique [0002] The laser collimator is a basic reference tool in the laser system. For the convenience of use, there are often two focal planes, one is the transmitting focal plane, and the other is the receiving focal plane. The two focal planes are conjugate and located in the collimator. The real focal plane is the basic requirement for its use. How to adjust the two focal planes to their conjugate positions is a key problem that needs to be solved when the instrument is installed. The usual method uses the joint adjustment of the focal plane and the light pipe, which takes a long time to adjust. The adjustment is inconvenient and the repeatability is poor. Contents of the invention [0003] The invention proposes a method for adjusting the conjugate of the bifocal plane of a laser collimator, which can realiz...
