Integrated image sensor and lens assembly

摘要

An integrated image sensor and lens assembly includes a lens barrel adhered to a lens holder or a lens barrel adhered to an image sensor assembly using an adhesive. The lens barrel and lens holder or the lens barrel and the image sensor assembly are bonded based on the sheer strength of the adhesive. Thus, adhesive expansion does not substantially affect the distance between the lens and the image sensor and therefore does not affect the focal plane of the assembly.

主权项

1. An integrated image sensor and lens assembly comprising:
an image sensor substrate comprising an image sensor in an image plane; a lens holder comprising:
a base portion including a recess to partially enclose an image sensor assembly housing the image sensor; anda tube portion extending from the base portion in a direction of an optical axis substantially perpendicular to the image plane, the tube portion having a channel; a lens barrel having a first portion extending into the channel of the tube portion, and a second portion outside the channel of the tube portion, the second portion having a camera lens window; and an adhesive ring formed between an interior side surface of the tube portion of the lens holder and an exterior side surface of the first portion of the lens barrel inside the channel of the tube portion, the interior surface of the lens holder and the exterior surface of the lower portion of the lens barrel each oriented in a direction substantially parallel to the optical axis, the adhesive ring to radially bond the first portion of the lens barrel to the lens holder.
