Abstract
An electronic device includes at least one lens, an image sensor aligned along an optical axis from the at least one lens, and a reflective and refractive member disposed between the at least one lens and the image sensor on the optical axis. The reflective and refractive member includes an incident surface on which light passing through the at least one lens is incident, a first reflective surface inclined with respect to the incident surface, and a second reflective surface inclined with respect to the incident surface and spaced apart from the first reflective surface. First and second cutting planes are inclined with respect to the incident surface and face first and second directions, respectively.

An electronic device comprising:
- a camera module comprising at least one lens, an image sensor aligned along an optical axis from the at least one lens, and a reflective and refractive member disposed on the optical axis between the at least one lens and the image sensor,
- wherein the reflective and refractive member comprises:
- an incident surface that is perpendicular to the optical axis and on which light passing through the at least one lens is incident;
- a first reflective surface inclined with respect to the incident surface;
- and
- a second reflective surface inclined with respect to the incident surface and spaced apart from the first reflective surface;
- an exit surface parallel to the incident surface;
- a first cut side between the incident surface and the first reflective surface that is inclined at a first angle with respect to the optical axis and is formed at a first edge of the first reflective surface;
- and
- a second cut side between the exit surface and the second reflective surface that is inclined at a second angle with respect to the optical axis and is formed at a second edge of the second reflective surface,
- wherein the first cut side faces in a first direction,
- wherein the second cut side faces in a second direction different from the first direction,
- wherein the at least one of the first angle or the second angle is greater than zero (0) degrees and less than ninety (90) degrees, and
- wherein an absolute value of the first angle between the optical axis and the first cut side is greater than 5 degrees and less than 50 degrees.
An electronic device comprising:
- a camera module comprising at least one lens, an image sensor aligned along an optical axis from the at least one lens and at least one reflective and refractive member on the optical axis between the at least one lens and the image sensor,
- wherein the camera module forms a folded optical lens system in which a path of light incident on the at least one lens is reflected or refracted at least two times,
- wherein, among the at least one reflective and refractive member, a first reflective and refractive member closest to an image side of the image sensor comprises an incident surface that is perpendicular to the optical axis and where light passing through the at least one lens is incident, a first reflective surface that is inclined with respect to the incident surface, a second reflective surface that is inclined with respect to the incident surface and spaced apart from the first reflective surface, an exit surface parallel to the incident surface, a first cut side between the incident surface and the first reflective surface that is inclined at a first angle with respect to the optical axis and is formed at a first edge of the first reflective surface, and a second cut side between the exit surface and the second reflective surface that is inclined at a second angle with respect to the optical axis and is formed at a second edge of the second reflective surface,
- wherein the first cut side faces in a first direction,
- wherein the second cut side faces in a second direction different from the first direction,
- wherein the at least one of the first angle or the second angle is greater than zero (0) degrees and less than ninety (90) degrees, and
- wherein an absolute value of the first angle between the optical axis and the first cut side is greater than 5 degrees and less than 50 degrees.
