Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 1:
2. The device according to claim 1, wherein the first optical path assembly comprises: a beam splitter and a light homogenizing assembly arranged in sequence along the laser wavelength measurement optical path, wherein,
the beam splitter is configured to reflect a portion of the laser beam emitted by the laser device to the laser wavelength measurement optical path;
the light homogenizing assembly is configured to homogenize the laser beam reflected by the beam splitter to the laser wavelength measurement optical path; and the homogenizing assembly comprises: an optical light homogenizing element, a first convergent mirror and a reflecting mirror arranged in sequence along the laser wavelength measurement optical path, wherein,
the optical light homogenizing element is configured to homogenize the laser beam, so as to reduce an influence of a quality of the laser beam on a measurement precision;
the first convergent mirror is configured to converge the laser beam homogenized by the optical light homogenizing element to the second optical path assembly; and
the reflecting mirror is configured to reflect the laser beam converged by the first convergent mirror to the second optical path assembly.
