Problems solved by technology

This means that to write on a changing flat plane on a contact lens, it must first be flattened, often causing the material to wrinkle and / or deform

Embodiment Construction

[0032] Scanning solutions required for femtosecond micromodification of contact lenses include custom optical solutions using galvo scanners to cover the entire optical field. In this disclosure, micro-modifications of contact lenses can be written in their natural curved configuration, as it has been shown that creating objectives for imaging or writing on curved surfaces can significantly reduce the complexity of the required objectives (e.g., See "The optical advantages of curved focal plane arrays (the optical advantage of the curved focal plane array)" written by Rim, S.-B. et al. ("Optics Express", 2008.16(7): Page 4965-4971)), such is more beneficial.

[0033] This disclosure describes the optical design of a microscope objective and relay system for a two-DOF galvanometer scanning system, such as figure 1 shown schematically. The first vibrating mirror 111 and the second vibrating mirror 112 rotate around orthogonal axes, the first vibrating mirror 111 and the second...

Abstract

A pre-objective two-degree-of-freedom galvanometer scanning system including two galvo mirrors (111,112) with an optical relay (120) between the mirrors (111,112) and a microscope objective (130) witha curved image plane (140) is presented. The second galvo mirror (112) is located in the aperture stop before the objective. The optical system enables scanning in both directions over the full, curved field for creating custom refractive structures across the 6.5 mm optical zone of contact lenses using femtosecond micro-modification.

Description

[0001] Statement Regarding Federally Sponsored Research or Development [0002] This invention was made with government support under IIP 1549700 awarded by the National Science Foundation. The government has certain rights in this invention. technical field [0003] The invention is aimed at the optical design of the microscope objective lens and the relay system for the two-degree-of-freedom galvanometer scanning system. Two mirrors rotating about orthogonal axes are placed at two separate locations in the optical system with a relay step between them to enable bi-directional scanning across the curved field. Background technique [0004] Targeted optical materials have been shown to be particularly well suited to pulsed lasers operating under specific physical conditions that can generate local refractive index changes in the optical material without damaging the material in a way that could impair vision. The energy range, although above the nonlinear absorption thresh...
