Aspheric condensing lens 90 D
The 90 D lens is used at the slit lamp to view the retina and the optic disc. It gives a wider view than the 78 D lens (94° against 88°), so you get a quick overview of the fundus.
The aspheric surface keeps the image sharp and rich in contrast towards the edge. The working distance is short (5 mm), so hold the lens close to the eye.
