The optical element has a front surface, a back surface, a rim, and an angled portion of the rim. The source emits light in a first band of light and is configured to illuminate a portion of an eye of a user of the eyewear device. The dichroic mirror is arranged proximate to the angled portion of the rim, is reflective in the first band of light, is transmissive in a second band of light, and is configured to direct light in the first band reflected from the portion of the eye toward a first position. The camera is located in the first position that is located in a plane of the optical element, and the camera is configured to capture images of the light in the first band reflected by the dichroic mirror."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Embedded eye tracker with dichroic mirror","description":"An eyewear device has an optical element, a source, a dichroic mirror, and a camera.
