Claim 22:
23. The lens assembly according to claim 15, wherein the reflection component further has a first light-passable opening and a second light-passable opening that are surrounded by the light-blocking membrane layer, and the first light-passable opening is closer to the optical path than the second light-passable opening;
wherein a reference plane perpendicular to the optical path is defined, a projection area of the first light-passable opening on the reference plane is HAL a shortest distance between the first light-passable opening and the optical path on the reference plane is HD1, a projection area of the second light-passable opening on the reference plane is HA2, a shortest distance between the second light-passable opening and the optical path on the reference plane is HD2, and the following condition is satisfied:

0.02≤(HA2{circumflex over ( )}0.5/HD2)/(HA1{circumflex over ( )}0.5/HD1)≤0.98.
