Abstract

Claims (24)

1. A camera, comprising:

a lens having an optical axis (OA), N≥4 lens elements L 1 wherein 1≤i≤N and an effective focal length EFL, wherein a first lens element L 1 faces an object side and a last lens element L N faces an image side;

an image sensor; and

an optical path folding element (OPFE) for providing a folded optical path between an object and the image sensor, by folding light from a first optical path (OP1) that is parallel to the OA to a second optical path (OP2) that is perpendicular to the image sensor,

wherein the lens is located at an object side of the OPFE, wherein the EFL is in the range of 8 mm<EFL<50 mm, and wherein the OPFE is oriented at an angle β in the range of 45<β≤60 degrees with respect to the lens OA such that OP1 and OP2 form an angle of less than 90 degrees.

2. The camera of claim 1 , wherein 47<β≤55 degrees.

3. The camera of claim 1 , wherein 48<β<52.5 degrees.

4. The camera of claim 1 , the image sensor having a sensor diagonal SD, and wherein 0.45<SD/EFL<0.7.

5. The camera of claim 1 , wherein L 1 is made of glass.

6. The camera of claim 1 , wherein all the lens elements are made of plastic.

7. The camera of claim 1 , included in a camera module having a module height (MH) measured along OP1, wherein SD/MH>0.9.

8. The camera of claim 1 , included in a camera module having a module length (ML) measured along an axis perpendicular to OP1, wherein EFL/ML>0.9.

9. The camera of claim 1 , wherein the lens has a total track length (TTL) and a back focal length (BFL), and wherein BFL/TTL>0.7.

10. The camera of claim 1 , wherein 12 mm<EFL<20 mm.

11. The camera of claim 1 , wherein the image sensor has a sensor diagonal (SD), and wherein 7 mm<SD<10 mm.

12. The camera of claim 1 , wherein the lens has a f number (f/ #), and wherein the f/ #is in the range 2.0<f/ #<3.5.

13. The camera of claim 12 , wherein f/ #<2.9.

14. The camera of claim 1 , wherein N=4 and wherein a power sequence of lens elements L 1 , L 2 , L 3 , and L 4 is positive, negative, positive and negative.

15. The camera of claim 1 , wherein N=4 and wherein a power sequence of lens elements L 1 , L 2 , L 3 , and L 4 is positive, negative, positive and positive.

16. The camera of claim 1 , wherein the camera is included in a camera module, wherein the camera module has a first module region with a module region height (MH) measured along OP1 and a second shoulder region with a shoulder region height (SH) measured along OP1, and wherein MH>SH.

17. The camera of claim 16 , included in a camera module having a module height (MH) measured along OP1, wherein 6 mm<MH<13 mm.

18. The camera of claim 16 , wherein the camera has an aperture diameter (DA), and wherein DA>SH-3 mm.

19. The camera of claim 1 , wherein the camera is included in a mobile device.

20. The camera of claim 19 , wherein the mobile device is a smartphone.
