Description

Technical Field

[0001] The utility model relates to the field of molds, and more specifically to a plano-concave mirror support and a mold for manufacturing the plano-concave mirror support. Background Art

[0002] With the rapid development of AR / XR metaverse smart glasses, there is a potential market for smart glasses with optical degrees to meet the needs of specific customer groups. However, the current mainstream solution is to prepare AR / XR waveguide lenses with electrochromic functions and optical degrees through 3D printing technology, but because of its high price and limited production capacity, it cannot be popularized. For this situation, a plano-concave lens came into being. The plano-concave lens is an optical lens with one side being flat and the other side being concave. The plano-concave lens is bonded with an electrochromic lens and a waveguide to obtain an AR / XR waveguide lens with optical degrees. However, due to the characteristics of the lens and the setting of the optical center, the concave surface of the plano-concave lens is not a symmetrical concave surface. When the electrochromic lens needs to be bonded to the plane of the plano-concave lens, because the concave surface is facing downward, the plane of the plano-concave lens is not in a horizontal state, which is not conducive to the later bonding.
