SCANNING LENS AND ELECTRONIC DEVICE ASSEMBLY

Abstract

An imaging lens assembly includes a plastic optical element. The plastic optical element includes an incidence surface, a reflection surface, an exit surface, and a connecting surface. Image light enters the plastic optical element through the incidence surface, changes its direction of propagation through the reflection surface, and exits the plastic optical element through the exit surface. The connecting surface connects the incidence, reflection, and exit surfaces and includes a gate remnant, a diverging nozzle surface, and a cut-off remnant. The gate remnant is located on the connecting surface and is raised relative to an adjacent portion.The diverging nozzle surface is connected to the gate remnant and the adjacent portion, and diverges and extends from the gate remnant into the adjacent portion. The shear remnant is arranged on a surface of the gate remnant.
