Annular optical component, camera lens and image capturing unit

A camera lens, comprising:

• an imaging lens assembly comprising an object-side lens element and an image-side lens element;
• and
• an annular optical component disposed between the object-side lens element and the image-side lens element, the object-side lens element disposed on an object-side direction of the annular optical component, the image-side lens element disposed on an object-side direction of the annular optical component, the annular optical component comprising a plastic element and a metal element disposed on the plastic element, the plastic element comprising a plastic part, and the metal element comprising a metal part;
• wherein the plastic part comprises at least part of an inner annular surface of the annular optical component, the plastic part surrounds a central axis of the annular optical component so as to form a central opening, an outer annular surface of the annular optical component and the inner annular surface are opposite to each other, an object-side surface of the annular optical component faces an object-side direction of the annular optical component and is connected to the outer annular surface and the inner annular surface, an image-side surface of the annular optical component faces an image-side direction of the annular optical component and is connected to the outer annular surface and the inner annular surface, and the image-side surface and the object-side surface are opposite to each other;
• wherein the metal part of the metal element extends from the outer annular surface to at least one of the object-side surface and the image-side surface, and the metal part on one of the object-side surface and the image-side surface is exposed.
