Abstract
The utility model discloses a lensometer diopter collimation adjusting device. The device comprises a shell. The front end part of the shell is provided with a collimation objective lens. The rear end part of the shell is provided with a supporting seat adapted to a standard lens. A collimation adjusting objective lens capable of moving along the axial direction is arranged between the collimation objective lens and the supporting seat. The axes of the collimation objective lens, the collimation adjusting objective lens, and the supporting seat are superposed. During the assembling and utilizing process, the standard lens is placed on the supporting seat and the collimation adjusting objective lens is controlled to move along the axial direction, thereby adjusting the relative distance between the collimation objective lens and the collimation adjusting objective lens and thus accurately adjusting the diopter. At the same time, the lensometer diopter collimation adjusting device is simple in structure; the processing difficulty level of components of the lensometer diopter collimation adjusting device is low; and the assembling process of the lensometer diopter collimation adjusting device is simple and convenient.
