Assignee: META PLATFORMS TECHNOLOGIES, LLC
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 4:
5. A device, comprising:
a first-type liquid crystal (LC) lens configured to provide a first optical power that is variable in a first step resolution; and
a second-type LC lens coupled with the first-type LC lens, and configured to provide a second optical power that is variable in a second step resolution,
wherein the first step resolution is smaller than the second step resolution,
wherein a total optical power of the device is a sum of the first optical power and the second optical power, and is variable in the first step resolution,
wherein the first-type LC lens includes a first LC lens and a second LC lens arranged in optical series,
wherein the first LC lens is configured to provide the first optical power for a linearly polarized light having a first polarization direction, and
wherein the second LC lens is configured to provide the first optical power for a linearly polarized light having a second polarization direction that is orthogonal to the first polarization direction.
