LENS CONTROL AND ADJUSTMENT DEVICE Russian patent published in 2014 - IPC G02B27/62 

FIELD: physics.

SUBSTANCE: device has a table with a grid, tool attached to the table for measuring the displacement value thereof and a recorder of the position of the image of the grid, projected by the adjusted lens in an image plane, the recorder being connected to an imaging device. The table is capable of moving along the optical axis of the controlled lens. The device is provided with a tube placed between the table with the grid and the image plane of the grid, the tube having a reference base surface and a thread for fastening the controlled lens. The grid is placed on the table at a nominal distance from the reference base surface of the tube and is capable of moving in a perpendicular direction relative to the axis of the thread of the tube. The recorder of the position of the image of the grid is mounted in the tube in the image plane at a nominal distance from the reference base surface of the tube, is central relative to the axis of the thread of the tube and is capable of moving along that axis.

EFFECT: wider range of controlled lens parameters and types of lenses by controlling misalignment of optical and mechanical axes and the height of the microlens, while simplifying the design of the device.
