  • Device for optical imaging
    Patent number: 9383557
    Abstract: A device for optically imaging at least part of an object onto an area of a digital image sensor includes an optical channel, which includes a first imaging lens arranged on a first substrate, a second imaging lens arranged on a second substrate, and a field lens arranged on a third substrate. The first and second imaging lenses are identical and arranged such that a first surface of the first imaging lens is a light entry surface of the optical channel and that a first surface of the second imaging lens is a light exit surface of the optical channel. The field lens is arranged between the first imaging lens and the second imaging lens such that an axis running perpendicularly to the lateral extension of the optical channel and through a lateral center of the field lens forms a symmetry axis of the optical channel.
