Patent ID: 8842981

Claim:
An adapter for holding a camera lens of a smartphone, digital mobile device or other camera-bearing device in alignment with an optical instrument comprising: an optical instrument coupler having a pair of spaced-apart optical instrument clamp members, at least one of which is adapted to clamp an eyepiece of an optical instrument; a camera-bearing device coupler having a device clamp member which is adapted to clamp a linear edge of a camera-bearing device; a mounting plate for holding the optical instrument coupler in alignment with the camera-bearing device coupler so that a camera lens on the camera-bearing device is in optical alignment with the eyepiece of the optical instrument to be clamped by the optical instrument coupler, wherein the linear edge of the camera-bearing device to be clamped by said device clamp member is indicative of a horizon line of an image to be viewed through the camera lens of the camera-bearing device, wherein said pair of spaced-apart optical instrument clamp members are aligned relative to said device clamp member so that the horizon line for the image to be viewed through said optical instrument is aligned with the camera lens of the camera-bearing device, and wherein said pair of spaced-apart optical instrument clamp members is adapted to be clamped onto a pair of eyepieces of a binocular instrument.
