A system for high-resolution, wide-angle viewing of a retina comprising: an ophthalmic microscope having a lens arrangement for viewing images formed from a beam of light reflected from an eye, the lens arrangement of the ophthalmic microscope being configured to resolve an image of the anterior of the eye; a front lens attachment configured to alternatively position a lens holder into and out of the beam of light; a wide field of view optical system (120, 320, 520, 520') including: a first lens (122, 322, 522, 522') having a diffractive surface on at least one surface of the first lens; a second lens (126, 326, 526), wherein the first lens (122, 322, 522, 522',) and second lens (126, 326, 526) combine to form a substantially achromatic doublet, the first and second lens being configured to resolve an image of the retina of the eye when used in combination with the lens arrangement of the ophthalmic microscope; and a shared housing (130, 530, 530') configured to house the first lens (122, 322, 522, 522') and the second lens (126, 326, 526) and configured to couple with the lens holder such that, when the lens holder is positioned in the beam of light, the first lens (122, 322, 522, 522') and the second lens (126, 326, 526) are positioned coaxially with the beam of light and allow the ophthalmic microscope to view a high-resolution image of the retina of the eye. an ophthalmic microscope having a lens arrangement for viewing images formed from a beam of light reflected from an eye, the lens arrangement of the ophthalmic microscope being configured to resolve an image of the anterior of the eye; a front lens attachment configured to alternatively position a lens holder into and out of the beam of light; a wide field of view optical system (120, 320, 520, 520') including: a first lens (122, 322, 522, 522') having a diffractive surface on at least one surface of the first lens; a second lens (126, 326, 526), wherein the first lens (122, 322, 522, 522',) and second lens (126, 326, 526) combine to form a substantially achromatic doublet, the first and second lens being configured to resolve an image of the retina of the eye when used in combination with the lens arrangement of the ophthalmic microscope; and a shared housing (130, 530, 530') configured to house the first lens (122, 322, 522, 522') and the second lens (126, 326, 526) and configured to couple with the lens holder such that, when the lens holder is positioned in the beam of light, the first lens (122, 322, 522, 522') and the second lens (126, 326, 526) are positioned coaxially with the beam of light and allow the ophthalmic microscope to view a high-resolution image of the retina of the eye. a first lens (122, 322, 522, 522') having a diffractive surface on at least one surface of the first lens; a second lens (126, 326, 526), wherein the first lens (122, 322, 522, 522',) and second lens (126, 326, 526) combine to form a substantially achromatic doublet, the first and second lens being configured to resolve an image of the retina of the eye when used in combination with the lens arrangement of the ophthalmic microscope; and a shared housing (130, 530, 530') configured to house the first lens (122, 322, 522, 522') and the second lens (126, 326, 526) and configured to couple with the lens holder such that, when the lens holder is positioned in the beam of light, the first lens (122, 322, 522, 522') and the second lens (126, 326, 526) are positioned coaxially with the beam of light and allow the ophthalmic microscope to view a high-resolution image of the retina of the eye.
