Compact folded camera
Folded cameras comprising a movable lens having a lens optical axis and positioned in an optical path between an optical path folding element (OPFE) and an image sensor, wherein the OPFE folds light from a first direction to a second direction, the second direction being substantially along the lens optical axis, and an actuator for controlled lens movement, the actuator including or being attached to a shield partially surrounding the lens, the shield having an opening positioned and dimensioned to enable installation of the lens into the shield from an insertion direction substantially parallel to the first direction. A folded camera disclosed herein may be included together with an upright camera in a dual-camera.
1. A method for assembling a folded camera, comprising:
a) providing an actuator for the folded camera, the actuator having a shield;
b) inserting a lens of the folded camera into the actuator through an opening in the shield, the lens having a lens optical axis;
c) inserting an optical path folding element (OPFE) into the actuator, wherein the OPFE folds light arriving from a first direction to a second direction, wherein the top surface of the shield faces the light from the first direction and wherein the lens optical axis is substantially parallel to the second direction;
d) covering the shield opening with a lid; and
e) attaching an image sensor of the folded camera to the actuator such that it lies in a plane substantially perpendicular to the optical axis.
2. The method of claim 1 , wherein the covering the shield opening with a lid includes fixedly attaching the lid to the shield.
3. The method of claim 1 , wherein the opening is a top opening in the shield, and wherein the inserting the OPFE into the actuator includes inserting the OPFE from a top surface of the actuator.
4. The method of claim 1 , wherein the opening is a top opening in the shield, and wherein the inserting the OPFE into the actuator includes inserting the OPFE from a bottom surface of the actuator.
5. A method for assembling a folded camera, comprising:
a) providing an actuator for the folded camera, the actuator having a shield and a base separated into a back base part and a front base part;
b) inserting a lens of the folded camera into the actuator through an opening in the shield, the lens having a lens optical axis;
c) inserting an optical path folding element (OPFE) into the actuator back base part, wherein the OPFE folds light arriving from a first direction to a second direction, wherein the top surface of the shield faces the light from the first direction and wherein the lens optical axis is substantially parallel to the second direction;
d) attaching the back base part to the front base part;
e) covering the shield opening with a lid; and
f) attaching an image sensor of the folded camera to the actuator such that it lies in a plane substantially perpendicular to the optical axis.
