  • Publication number: 20200409016
    Abstract: A manufacturing method of an imageable optical device includes pre-positioning at least two lens components along the optical axis so that the at least two lens components are able to form an image. A first structural gap and a second structural gap are arranged at different positions between two adjacent lens components. The method also includes adjusting relative positions of the pre-positioned at least two lens components by active alignment, arranging a first adhesive in the first structural gap, arranging a second adhesive in the second structural gap, and sequentially curing the first and second adhesives. The influence of later steps of the manufacturing process on the imageable optical device may thus be reduced, and connection strength and reliability of the imageable optical device are improved by subsequently curing the second adhesive. Also provided are an optical lens having an air escape channel, and an assembly method thereof.
