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 folded camera, comprising:
a movable lens barrel comprising lens elements 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;
an actuator for controlled lens movement, the actuator including a shield partially surrounding the lens barrel and having an opening positioned and dimensioned to enable installation of the lens barrel into the shield from an insertion direction substantially parallel to the first direction, and
a lens carrier for holding the lens barrel, the lens carrier having a V-groove structure for mechanically positioning the lens barrel in a correct position during installation.
2. The folded camera of claim 1 , wherein the folded camera has a height not exceeding the lens barrel height by more than 800 μm.
3. The folded camera of claim 2 , wherein the folded camera has a height not exceeding the lens barrel height by more than 700 μm.
4. The folded camera of claim 2 , wherein the folded camera has a height not exceeding the lens barrel height by more than 600 μm.
5. The folded camera of claim 1 , wherein the image sensor is wire bonded to a printed circuit board with wire bonds located on sides of the image sensor that are substantially parallel to the first direction.
6. A dual-camera comprising the folded camera of claim 1 and a non-folded camera.
7. A folded camera, comprising:
a movable lens barrel comprising lens elements 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;
an actuator for controlled lens movement, the actuator including a shield partially surrounding the lens barrel and having an opening positioned and dimensioned to enable installation of the lens barrel into the shield from an insertion direction substantially parallel to the first direction;
a lens carrier for holding the lens barrel, the lens carrier having a V-groove structure for mechanically positioning the lens barrel in a correct position inside the shield; and
a lid having a first lid thickness and covering the shield, wherein the folded camera has a camera height substantially equal to a sum of the lens barrel height, the first lid thickness, the shield thickness, the size of a first air gap between a first point on a surface of the lens barrel facing the lid and the size of a second air gap being between a second point on a surface of the lens barrel diametrically opposed to the first point and facing the shield.
8. The folded camera of claim 7 , wherein the other of the top or bottom parts of the shield includes a respective second opening covered by a lid with a respective second lid thickness, wherein the second air gap is between the second point and the second lid and wherein the second lid thickness replaces the shield thickness.
9. The folded camera of claim 7 , wherein each of the first and second air gaps is in the range of 10-50 μm.
10. The folded camera of claim 7 , wherein each of the first and second air gaps is in the range of 10-100 μm.
11. The folded camera of claim 7 , wherein each of the first and second air gaps in the range of 10-150 μm.
12. The folded camera of claim 7 , wherein the opening in the shield is dimensioned to enable insertion of the lens barrel into the shield in a direction parallel to the first direction and perpendicular to the lens optical axis.
13. The folded camera of claim 7 , wherein the image sensor is wire bonded to a printed circuit board with wire bonds located on sides of the image sensor that are substantially perpendicular to the lid and to the surface of the lens barrel diametrically opposed to the first point and facing the shield.
14. The folded camera of claim 7 , wherein the movable lens barrel is movable for focusing.
15. The folded camera of claim 7 , wherein the movable lens barrel is movable for optical image stabilization.
