DescriptionThis excellent mid-power lens provides medium field and magnification, with an ideal diameter for grip and manipulation in the orbital area.The 15D provides high magnification along with an optimized working distance from the cornea. With its 4.11x magnification it is also well suited for disc and macular observation.Volk’s state-of-the-art 20D diagnostic/laser lens is perfectly corrected for field curvature, astigmatic aberrations and coma – delivering the best retinal image of any 20 diopter lens on the market. Its advanced double aspheric design further With advanced glass technologies and designs, the Digital ClearField lens delivers enhanced wide field views of the mid and far peripheral retina. Using this advanced lens will provide image quality previously unattainable with the binocular indirectThe Pan Retinal® 2.2 uniquely combines magnification nearly that of the 20D lens with a field of view approaching that of the 30D lens. Excellent for virtually every examination procedure, including small pupil examinations.
