A Glimpse Into How Nikon Produces the Optical Glass Used in Its Lenses

Nikon recently put out this short 3-minute video that offers an interesting glimpse into one of the critical steps of lens making: the production of the optical glass. It steps through the various stages of manufacturing, from combining the raw elements through examining the chunks of glass before they’re polished and perfected.





We’re shared a few behind-the-scenes videos showing lens manufacturing in the past, including one that shows how Canon’s 500mm f/4L lens is made and one that shows how Leica creates theirs.

P.S. In case you’re wondering, the video was captured using a Nikon D800.
