摘要： PURPOSE:To adjust the laser light projection position of a work lens by off machine by arranging the work lens for laser on the optical path of the visible laser light shaped in a cylindrical light and adjusting so that a focus point may become in the same axis as the center axis of the cylindrical light with giving a rotation to the lens. CONSTITUTION:The visible laser light 12 oscillated by an He-Ne laser device 11 is shaped in a cylindrical light 17 by the optical mechanism 18 consisting of a mirror 13, rotary mirror 14 and lens 16. The cylindrical light 17 is made incident on the work lens 19 for laser held on a work lens holder holding means 27 to project a condensed transmission light 30 on the photodetection face 32 of a photodetecting means 31. At this time the transmission light 30 is condensed as a condensing point on the photodetecting face 32 by adjusting the position of the photodetecting means 31. The condensing point by the lens 19 is adjusted so as to become the same axis as the center axis of the cylindrical light 17 with rotating the work lens holder 20. The projection position of the work lens can thus be adjusted in an off machine state for a laser machine.

摘要： PURPOSE:To measure the focal length of a work lens by off machine by providing the work lens for laser and photodetecting means on the optical path of the visible laser light shaped in a cylindrical light and reading a focus position based on the annular pattern of a transmitting light. CONSTITUTION:The visible laser light 2 by an He-Ne laser device 1 is shaped by the optical mechanism 8 consisting of mirrors 3, 4 and a lens 6 in a cylindrical light 7. The cylindrical light 7 is then made incident on the work lens 9 for laser held on a work lens holder 10 to project a transmitting light 12 on the photodetecting face 14 of a photodetecting means 13. At this time the annular pattern of the transmitting light 12 on the photodetecting face 14 is observed at both positions A, C in the vertical direction of a focus position B to read the distance DB of the focus position B based on the distances DA, DC from the reference position of each position A, C. The difference in the visible light and the laser light for working is corrected further at the read focus position of the lens 9. The focal length of the work lens can thus be adjusted in an off machine state for a laser machine.
