[0002] The photolithography lens is a lens device used for imaging the target surface, but the existing photolithography lens still has shortcomings. Specifically, the light path of the existing photolithography lens is that the incident light is in the horizontal direction, passes through the vertically placed half-lens, passes through the three lenses above vertically upward through the 45-degree placed reflector, and is reflected vertically downward through the four lenses until it reaches the bottom imaging surface to form an image. Due to the high precision of the photolithography lens, the accuracy of the placement of all lenses is also extremely high, and the position adjustment of the half-lens is relatively inconvenient.
[0003] Therefore, a device for adjusting a vertically mounted half-lens mirror is needed to solve the problems raised in the above background technology. Utility Model Content

[0014] 1. In the utility model, a device for adjusting a vertically mounted half-lens lens is designed. The adjustment mechanism in the device is used to adjust the position of the half-lens. The center positions of the two hemispheres of the vertical half-lens are measured. Adjustment shims are inserted between the downward adjustment bar and the base plate, and the number of inserted adjustment shims is changed to change the vertical up and down position of the half-lens. If horizontal translation is required, the lower adjustment screws corresponding to the lower adjustment bar on the six groups of right-angle adjustment blocks are rotated respectively. After adjustment is in place, the connecting screws between the lower adjustment bar and the base plate are tightened to move the half-lens in the horizontal direction. Then, the vertical half-lens is adjusted. The horizontal rotation position is achieved by rotating the upper adjustment screws corresponding to the upper adjustment bars on the 6 groups of right-angle adjustment blocks to push the half-lens to rotate horizontally, thereby completing the position adjustment of the half-lens. The adjustment process has high precision, which solves the problem that the light path of the existing photolithography lens is that the incident light is in the horizontal direction, passes through the vertically placed half-lens, passes vertically upward through the three lenses above through the 45-degree placed reflector to the top concave mirror, and then passes vertically downward through the four lenses to the bottom imaging surface. Due to the high precision of the photolithography lens, the precision of the placement of all lenses is also extremely high, and the position adjustment of the half-lens is relatively inconvenient.
