Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include three lens elements with refractive power, with a light folding element such as a prism, located between a first lens element on the object side of the lens system and a second lens element, that redirects the light refracted from the first lens element from a first axis onto a second axis on which the other lens elements and a photosensor are arranged. The lens systems may include an aperture stop located behind the front vertex of the lens system, for example at the first lens element, and an optional infrared filter, for example located between the last lens element and a photosensor.

Abstract: A folded lens system that includes lenses with refractive power and two light folding elements such as prisms. A first lens on a first axis refracts light to a first folding element. The first folding element redirects the light from the first axis onto a second axis on which one or more lenses are arranged. The lenses on the second axis refract the light to a second folding element. The second folding element redirects the light onto a third axis on which a sensor is disposed. The lens system may include a front aperture. The sensor may be moved on the third axis to provide autofocusing, or alternatively the lens system may include one or more optical actuators that provide autofocusing. The lens system may have a low F-number (

Abstract: Compact folded lens systems are described that may be used in small form factor cameras. Lens systems are described that may include four lens elements with refractive power, with a light folding element such as a prism, located between a first lens element on the object side of the lens system and a second lens element, that redirects the light refracted from the first lens element from a first axis onto a second axis on which the other lens elements and a photosensor are arranged.

Abstract: An optical system for operation at a target near-infrared (NIR) wavelength in imaging an object onto an image plane. The system includes the following optical elements, arranged in order from object side to image side: a first lens, including a first material having a first index of refraction at the target NIR wavelength and having a positive refractive power; a second lens comprising the first material and having a meniscus shape; a third lens comprising the first material and having a meniscus shape; and a fourth lens, including a second material having a second index of refraction at the target NIR wavelength that is lower than the first index of refraction, and having front and rear surfaces of an aspheric form. The aspheric coefficients are chosen so that rays are not totally internally reflected within the fourth lens to impinge on the image plane.
