Document Type and Number:
WIPO Patent Application WO/2020/038161
Kind Code:
A1
Abstract:
An optical lens, a photographing module and an assembly method. The optical lens comprises a first lens unit (100), a second lens unit (200) and a first adhesive material (300). The first lens unit (100) comprises at least one first lens (101). The second lens unit (200) comprises a second lens barrel (202) and at least one second lens (201). The second lens unit (200) has a second optical region and a second structure region. The second structure region has a second top surface (2021). The second top surface (2021) has a recess (2020). The first adhesive material (300) is positioned in a first gap (400) between the first lens unit (100) and the second lens unit (200), and is received in the recess (2020). The first adhesive material (300) flows in the recess (2020) before being cured. The assembly method can reduce assembly errors, thereby improving imaging quality.
