Abstract
An reconfigurable optical arrangement for imaging posterior and anterior surfaces of a visual system. The optical arrangement includes a relay containing first and second lenses each having a positive optical power and detachably cooperated with one another such that the first lens and the second lens form an afocal system configured to form a conjugate relationship between the first plane and the second plane. In a related embodiment, the optical arrangement may include a first lens system of an first optical system housed in a body of a mobile telecommunication device and an afocal relay including first and second lenses that possess equal optical properties. Here, the afocal relay is configured to have a unity magnification and to provide diffraction-limited imaging within a spectral range from at least 486 nm to at least 656 nm. The method for imaging with the use of the optical arrangement.
