The Philosophy of Nikkor is a series of videos which Nikon started to release in April of last year. Every so often a new video is released containing insight into the creation of their Nikkor lenses. There are interviews with everybody from the designers and product managers right down to those making the individual components.
In the latest video, Volume 6 released recently, we hear from those who make the optical glass. As part of the Nikon Group, Hikari Glass produces the optical glass that will eventually go into the Nikkor lenses you mount to your camera. The current Hikari Glass plant was built in 1975 in Akita, Japan. It’s a fascinating look at how our lenses begin their life.
