Techniques are described for time-of-fly sensors with hybrid refractive gradient-index optics. Some embodiments are for integration into portable electronic devices with cameras, such as smart phones. For example, a time-of-fly (TOF) imaging subsystem can receive optical information along an optical path at an imaging plane. A hybrid lens can be coupled with the TOF imaging subsystem and disposed in the optical path so that the imaging plane is substantially at a focal plane of the hybrid lens. The hybrid lens can include a less-than-quarter-pitch gradient index (GRIN) lens portion, and a refractive lens portion with a convex optical interface. The portions of the hybrid lens, together, produce a combined focal length that defines the focal plane. The hybrid lens is designed so that the combined focal length is less than a quarter-pitch focal length of the GRIN lens portion and has less spherical aberration than either lens portion.

Provided are an optical distance measuring apparatus, which is capable of accurately measuring a distance, whatever the temperature may be, and which can be easily manufactured at low cost, and an electronic apparatus mounted with the optical distance measuring apparatus. A lead frame of the optical measuring apparatus has two or more first reinforcing terminals, each of which has a part extending in a direction substantially orthogonal to a direction in which a connecting part between a light emitting header and a light receiving header extends. The first reinforcing terminals are fixed by a first light blocking resin body and connected to the light receiving header.
