The present invention discloses a lens device suitable for the large-diameter lenses (with diameter &#x2265;100 mm) of a vertical setup, and its adjustment method. The aberration caused by the self-gravity of lenses and the deformation generated by the clamping stress of the fixing device is compensated.

The present disclosure illustrates a non-contact measurement device for a radius of curvature and a thickness of a lens and a measurement method thereof. The non-contact measurement device utilizes a non-contact probe to integrate a motor, an optical scale and an electronic control module, so as to achieve measurement for the radius of curvature and the thickness of the lens. The present disclosure adopts astigmatism to achieve fast and precise focusing. To overcome the spherical aberration problem, thickness measurement can be implemented by the non-contact measurement device through a formula calculation and utilization of a correction plate, wherein single one probe is used for the measurement herein. For the thicker lens, the non-contact measurement device can be extended to use dual probes, so as to detect the top and bottom sides of the lens.

Non-contact measurement device for radius of curvature and thickness of lens and measurement method thereof

A support device for supporting a lens includes a support component. The support component includes a main body, a plurality of first support portions and a plurality of second support portions. Each of the plurality of first support portions is disposed on the main body, has a first support position thereon having a first height, and is configured to rigidly support the lens. Each of the plurality of second support portions is disposed on the main body, has a second support position thereon having a second height, and is configured to flexibly support the lens. When a configuration relationship between the support component and the lens becomes a decoupling relationship, the second height is larger than the first height. When the configuration relationship is changed to a coupling relationship, an absolute difference value between the first and the second heights is less than a threshold.
