9. Ghosting, flares and transmission

In order to check the quality of the anti-reflection coatings, used in the new Nikkor, and to see how it renders the colours, we decided to employ an spectrophotometer and determine the lens’s transmission. The appropriate graph is presented below.

The graph doesn’t provide any reasons to complain. The transmission reaches a very high level of 95-96% and, what’s important, it does so for a wide range of wavelengths – from less than 500 to a bit over 700 nm. The loss of light is low and the colours – very natural. The efficiency of the coatings can be measured not by the overall transmission of an instrument, though, but by the amount of light we lose on one air-to-glass surface. In the case of the Nikkor AF-S Micro 60 mm f/2.8G ED we deal with nine groups of elements so as many as eighteen air-to-glass surfaces. It means on one such surface the tested lens loses just 0.25% of light and that result is reserved solely and only for coatings of the best quality.

When it comes to the work against bright light, good coatings are just a qualified success. The inner construction of the tube and the right damping down of the reflected light are equally important. Not everything is perfect here because in specific conditions the flares are visible. To get them, though, you have to put the Sun right into the frame and you must admit it is a bit extreme choice of conditions for a lens with such an angle of view and such applications.
