Systems And Methods For Light Lens Hot Stamping

摘要

The present disclosure provides systems and methods for fabricating a patterned lens through hot stamping techniques. In certain example embodiments, a lens material is placed in a heat press. The heat press includes at least one shim having a patterned surface. The shim is pressed onto the lens material with the patterned surface contacting the lens material. The heat press heats the lens material to malleability and the pattern of the shim is pressed into the lens material. The lens material is then cooled and a patterned lens is fabricated.

主权项

1. A method comprising the steps of:
receiving a lens material into a heat press, wherein the heat press comprises:
a first press bed;a first heat plate coupled to the first press bed, the first heat plate comprising a temperature control system;a first shim comprising a first side and a second side, the first side coupled to the first heat plate opposite the first press bed and the second side having a first pattern, wherein heat is conductive between the first heat plate and the first shim; anda second press bed aligned with respect to the first shim, wherein the lens material is disposed between the second press bed and the first shim; applying pressure to the lens material while disposed between the first shim and the second press bed; heating the lens material via heat provided to the first shim from the temperature control system of the first heat plate; and transferring a pattern corresponding to the first pattern of the first shim to the lens material, thereby forming a patterned lens.
