This lens provides a high-resolution view of the posterior pole and a sharper image across the diameter of the lens. The Digital 1.0 X Imaging Lens is also ideal for slit lamp photography. For best results during slit lamp photography, it is recommended that you use this lens with the Volk Steady Mount.
