It is possible to (i) cause a sixth lens to more effectively correct various aberrations and (ii) make an optical overall length shorter. A first lens (L) has positive refractive power. A fifth lens (L) and a sixth lens (L) each have negative refractive power. An object-side surface (LF) of the first lens (L) is a convex surface. At least one of an object-side surface and an image plane-side surface of each of a second lens (L), a third lens (L), a fourth lens (L), and the fifth lens (L) is an aspheric surface. An object-side surface (LF) of the sixth lens (L) is a concave surface and is an aspheric surface. An image plane-side surface (LR) of the sixth lens (L) is an optically planar surface throughout a region corresponding to an effective diameter of the image plane-side surface (LR) of the sixth lens (L).

Position adjustment device and position adjustment method

In order to realize a device and a method each capable of forming a lens with high accuracy and low costs, a lens forming device of the present invention includes a metal mold, an insulating substrate, a stage, a power source, a switch, and a UV radiating device. Dielectric resin is supplied onto the insulating substrate and a transfer surface of the metal mold is pressed to the dielectric resin so as to transfer a lens shape to the dielectric resin. At that time, the power source applies a voltage on the metal mold to generate an electric field between the metal mold and the insulating substrate so that an electrostatic attraction causes the dielectric resin to be attracted toward the transfer surface of the metal mold while the top of the dielectric resin has a sharp cuspate shape. Consequently, bubbles are less likely to be invade between the transfer surface and the dielectric resin, allowing transferring a highly accurate lens shape to the dielectric resin.
