CRT Nikkor-O 55mm f1.2 oscilloscope lens

This is another lens designed to record oscilloscope traces on a curved screen. It is optimized for close focusing, about half life size, and it is extremely sharp at that distance. However it has very strong field curvature (so that the entire trace is sharp) which makes it look quite strange at longer focusing distances. However it has a very characteristic bokeh that can be pleasing at closer focusing distances.
