Aspheric aberration continuous zooming miniature liquid core column lens system based on PDMS (Polydimethylsiloxane) substrate

The utility model discloses a PDMS substrate-based aspherical aberration continuous zoom miniature liquid core cylindrical lens system, which comprises a double-gluing cylindrical lens and a double-convex cylindrical lens which are embedded in the PDMS substrate, a liquid core is injected into the double-gluing cylindrical lens, the double-convex cylindrical lens is embedded in the PDMS substrate at the right side of the double-gluing cylindrical lens, and a diaphragm with the width of 2.80 mm is adhered to the left side surface of the PDMS substrate. When liquid with different refractive indexes is injected into a liquid core of the column lens system, the refractive index n of the liquid is changed from 1.3330 to 1.5530, the lens system designed by the utility model can realize the continuous change of the back focal length from 50.882 mm to 5.857 mm, and the zoom ratio is greater than 8; in the whole liquid zooming range, the root-mean-square radius of the lens system in the Y direction of the defocused sp
