Camera lens.
What the technical solution of the utility model was realized in：
A kind of CCD translation interfaces camera lens, including body tube and can opposite body tube rotation cam, it is characterised in that：Institute
State and microscope base is equipped with body tube, be equipped with lens set in the microscope base, the lens set is connected through guide pin component with cam, described convex
The limited block that side is equipped with adjustable position is taken turns, the limited block is spirally connected with body tube through nut, and the body tube front end is equipped with
Object lens protective cover, rear end are equipped with CCD protecting cover for joint, imaging sensor, the body tube are equipped with before the CCD protecting cover for joint
Inner surface is additionally provided with insulating layer.
As a kind of perferred technical scheme, the guide pin component includes lead ring and guide pin, and the lead ring is located on guide pin
On.
As a kind of perferred technical scheme, the body tube is provided with two wide guide grooves, for limiting lead ring
