Can the experts here teach me please. I was under the impression that glass for Swaro, Zeiss and Leica came from the Kamakura factory. The European Alpha glass companies got center pour then they all took that glass back home for their own cutting, polishing and coating techniques that they use.

Details are greatly appreciated. TIA
 
Can I ask why does it honestly matter? Are you going to stop using one of those or stop shopping for one of them if the glass isn't from that particular factory?

It matters because when the subject is discussed I want to be be 100% sure my info is correct. The internet is so full of disinformation these days and I'd just like to know is all. Just curious.

Example. Zeiss web page says they use Schott then on another Zeiss official web page it says " there is Schott factory and assembly plants in Japan". Could be mis speak as the talk optics and camera stuff.

I shop, based upon best bang for the buck noting that everyone's eyes are different and we all see things differently. What I have been having a hard time the past few weeks believing with my own two eyes is how close my NL Pures are compared to the girlfriends Maven B1.2

Makes me wonder a little if the Alpha glass is really as top notch as we think it is.

The thing most companies of all kinds don’t say out loud is components are less expensive coming from China. They may do final grinding or coatings, but nothing in consumer optics is a trade secret. Specialty optical glass is a commodity today.

The cost of all components and materials, of all levels of quality in China are less expensive. The American guys actually living and working in China who are familiar with the supply chains describe it as more closely integrated than what we have. If they need a mine, the government opens a mine and problem solved. They don’t have to wait for a profit maximizing private corporation to price gouge in order to open it. If they need electricity the government makes it happen. It’s really amazing that they have to import so many raw materials, but then process it and sell it at a price that is so much less than a profit maximizing economy like ours.

Many Japanese brands of all kinds, in all industries have been using Chinese parts for quite some time to save money.

Not related to this, but I just finished watching a video talking about misinformation Americans have been fed by media and pundits trying to sensationalize how poorly China is doing, especially how the workforce is aging out and there will be labor shortages. There are at least four times the population in every age range compared to the US, and the country as a whole is growing the middle class education and standard of living quickly, so there aren’t going to be labor shortages.

When China saw the writing on the wall about tariffs Trumps last term, they ramped up suppling farm equipment to developing areas around the world at 1/3 the cost of American brands for mutually beneficial long term commodity contracts. Hell, Americans don’t even like John Deere any more. China isn’t going to keep buying our commodities when their costs through partnerships in Brazil or Russia are much cheaper. There seems to be a lag in reporting about this, but when the wheat coming off the farm is already owned by the Chinese and not sold on the commodity markets, I bet it flies under the radar of commodity reporting.

I’m just rambling. . .

Back to optics, I have three Leupold Gold Ring binoculars out of the 1980s that are more clear than current production BX-4 models. They have cheaper components and manufacturing, supposedly better coatings, and still produce an inferior product to maximize family profits. A great example of a good family run company that goes down the tubes when heirs who don’t care other than getting a check from the hired out management team. Sad really. Really sad.
 
I'd agree that Leupold has slipped in quality as compared to other newer companies. I divested myself of almost all of the Leupold scopes I've owned. What a shame.

I believe I read somewhere else that Schott has a factory in China as well. Zeiss just put out media that they're not going to be producing anything in Germany, it's all going to be OEM'd by the factories in asia. All of Meopta is also going to come from China.

The "Alpha" companies have been using parts from China and Japan for decades, even if they're not openly admitting it. People can talk them up all they want, part of what you're buying is the name tag. That's not to say that they aren't great products, they obviously are.... but at this point they're not great enough to justify the difference in price from other quality makers. I'm curious, do you feel that the NL Pures are legitimately worth 3 times the price of the Maven, having both to compare?
 
schott glass is a good start but after that the treatments done make the whole differences ... i do remember some interesting discussions many decades ago already before to france with the differences with the same glass/lens coming from the same place and treatments made for zeiss or hensoldt. Swarovski and Kahles are using schott glass/lenses but use their own treatment and Kahles in the past were doing their own lens but that is long time ago. Schmidt & Bender is another example where the treatment of the lenses can vary depending of where the scope is going but i do not know anymore about in house works done or not since the PM versions.

Don’t know, don’t care. Respect your curiosity though. There was a thread on this awhile back. Quite a few replies along the same lines. There was some good details there though, for those interested.

Yeah I thought so. Looked for it but couldn't find it.

No I dont at all. I've looked through them both at dawn, mid day and last light for close to two weeks now off the back porch.
 
The alpha guys will come after me with their pitchforks, but truly I think the only big advantage the alpha glass brands has going for it is resale value, when compared to the top offerings from the companies like Tract, GPO, and Maven.
 
High end Zeiss comes from Schott Germany, low end China. Leica has German schott, Swarovski German schott, high end meopta has schott from Germany, I believe Kowa is low but finished in house, maven, vortex, leupold use komachura and low at varying levels from China and Japan. The old Leuopulds had German schott (gold ring binos and spotters).

Thank you.
 
Kowa’s fluorite crystal is grown in house and is a highly protected proprietary process. All products using Kowa fluorite crystal are manufactured start to finish by Kowa in Japan. They will not outsource manufacturing or assembly of these products. They are the only sporting optics company using pure fluorite crystal.

 
This paper on microscope objectives is interesting and describes some of the evolution of lens configuration as price goes up.

 
Great information from all. I do have to hand it to Kowa’s marketing department “pure synthetic fluorite” has a nice ring to it, but could mean just about anything. Companies are in the business of selling things so I’m not casting shade.

It would be fun to be a fly on the wall as boxes of optical glass are unpacked at different factories to see what language the cardboard boxes are printed in.
