The utility model adopts the following technical scheme:
the utility model provides a lens phase difference measurement tool, includes the fixing base, lens location rack interface that is used for pegging graft spacing has been seted up to fixing base one side, lens location rack has been inserted in the lens location rack interface, transversely insert spacing lens mounting groove has been seted up on the lens location rack, lens location rack is located the lens mounting groove outside and has been seted up transversely inserts spacing apron mounting groove, lens location rack is gone up lens mounting groove bottom and has been seted up the light-passing through mouth, lens mounting groove is used for settling the lens that awaits measuring, install the apron in the apron mounting groove, the unthreaded hole has been seted up on the apron, the apron is parallel with the lens that awaits measuring.
Preferably, the open end of the lens positioning and positioning rack insertion port is abutted against a stop.
Preferably, the lens positioning and setting frame, the cover plate, the fixing seat and the stop block are formed by cutting an aluminum plate.
Preferably, the cover plate has a thickness of 1-10mm.
Preferably, the lens positioning and arranging frame insertion port is matched and clung to the lens positioning and arranging frame.
The beneficial effects of the utility model are as follows: (1) The lens positioning and arranging frame is arranged, the lens to be detected is inserted into the lens positioning and arranging frame, meanwhile, the lens positioning and arranging frame is inserted into the lens positioning and arranging frame insertion port and is tightly attached through the stop block, so that the front, rear, left and right directions of the lens to be detected are limited, movement cannot occur in the detection process, detection errors are reduced, and the measurement time of detection personnel is shortened; (2) Meanwhile, the lens to be tested does not need to be in direct contact with clamping limit, so that scratch is reduced.
