Abstract: An imaging lens includes one or more lens elements configured to receive and focus light in a first wavelength range reflected off of one or more first objects onto an image plane, and to receive and focus light in a second wavelength range reflected off of one or more second objects onto the image plane. The imaging lens further includes an aperture stop and a filter positioned at the aperture stop. The filter includes a central region and an outer region surrounding the central region. The central region of the filter is characterized by a first transmission band in the first wavelength range and a second transmission band in the second wavelength range. The outer region of the filter is characterized by a third transmission band in the first wavelength range and substantially low transmittance values in the second wavelength range.

Abstract: A head mounted display system configured to project light to an eye of a user to display augmented reality images can include a frame configured to be supported on a head of the user, a camera disposed temporally on said frame, an eyepiece configured to direct light into said user's eye to display augmented reality image content to the user's vision field, a reflective element disposed on the frame, and at least one VCSEL disposed to illuminate said eye, wherein the camera is disposed with respect to the reflective element such that light from the VCSEL is reflected from the user's eye to the reflective element and is reflected from the reflective element to the camera to form images of the eye that are captured by the camera.
