G'Day All,

 

Happened to come across this article by chance alone. Speaking candidly, I've never given much thought to the manufacturing process behind optical glass although, having seen multiple pictures of lens components and prisms laid bare, I regard the end product in much the same manner a jeweller would an immaculately cut and polished diamond.

 

Truly fascinating!!

That takes me back !  I worked for Hoya Glass back in the early 80's.  Although I was in sales, they sent me to the glass

foundry outside of Tokyo for  6-weeks of training.  I was a green kid just 23,  right out of college.  I scooped sand, tended the

furnaces and crucibles, poured glass into the molds and all the way to final polish. 

Just like what's shown in the link.

 

It was hot sweaty work for the most part, but an experience I will always treasure.

Can't say that I've ever so much as stepped foot inside an optical glass factory, but I have had the good fortune of visiting the Ogishi Art Glass Factory in Australia's Hunter Valley.

The gallery is owned and operated by Setsuko Ogishi, a female Japanese Australian glass blower/artisan with a remarkable eye for beauty, colour and detail. Suffice it to say that it's not an easy discipline, especially given the hot and hazardous conditions necessary to facilitate her work.

Definitely worth a visit should anyone be planning a trip to Australia.

Thanks for that, I really enjoyed it.  Now comes grinding, polishing and coatings.  Another large step on the

way to a proper optical lens.

NDFarmer,

Not Nikon's Hikari Glass Factory I'm afraid, but a short video highlighting the capabilities of Meopta's optics factory in Czechoslovakia, including grinding, polishing and coating.
