Has anybody ever done a multi-coating of any camera lens after it's production, by taking it to a specialized shop for that kind of job? One day I was sitting and looking at my prescription glasses which were expensive and have cool emerald colored reflection, which are 10% of the brightness of another glasses which had no coating. I saw the same green reflection on my cheap Nikon lens, but never saw such coatings on old MF lenses, so I was wondering if that could be done, to maybe enhance already good lenses? |

I doubt you can do this at home. These processes are industrial scale and work on unassembled glass, and certainly would not be economical even if you could do them.
Plus I think a lensmaker has to tune the optical formula for these too, and doing it in your workshop you would probably immortalize any dirt, etc etc
What you can easily do is take black paper and build a lens hood for them. |

Cost is usually several hundred $ just for one lens element. And there is always risk that it gets damaged. Plus cost of taking the lens apart and later reassemble it correctly. I WOULD CERTAINLY NOT DO THAT. _________________ Klaus - Admin

Thirty years ago, here in Switzerland, it was possible to coat old lenses. I simply would have to bring the lens to my photo dealer who in turn sent it to a specialized workshop. polishing and re-coating would be CHF 80.-- per lens, at that time maybe 40 USD.
Probably that kind of service doesn't exist any more, but probably one could find here someone to do it even today.

That service has gotten rare, but still exists, but rather pricey! _________________ Klaus - Admin

Araxfoto in Kiev used to do that relatively cheap (less than 100$/lens). I've asked them ~2 years ago if they still do it, but the answer was "no, the factory sold the coating machine". If there is somebody else with a coating machine in Kiev it would be interesting to know.
Could you ask him for the price he is asking?
All the other coating services I could find at that time were either very expensive (several hundred dollars/lens) or they were industrial (cheap, but only accepting orders in the range of hundreds of lenses). |

No it is very difficult a process. In my country I had found a small lab in Milan who does this service for telescopes, after some long search. 30 euros per lens. Not only, lens had to be stripped and they didn't know how to do a stripping of the old coat: another telescope servicing lab told me to use nitric acid as suggested by internet sources. I tried it and the lens dissolved, it was probably plastic.
So if you want to coat a never coated lens yes you may try at some telescope making small lab. But if you need to re-coat an already coated lens you shall better know that there is no magic bullet, you will have to experiment with nitric acid dilutions (it is said to be a week long stripping or so).
And make sure you are stripping only glass lenses, mine was the front of a sixties yashinon DX and quickly dissolved ...
I found nitric acid on the italian amazon site. |

There are many suppliers in the US who do coating. I work for a laser company and am aware of a bunch. It requires special equipment (coating chamber) and is usually charged per run, so it would not be worth doing for just 1 or 2 elements. That and you'd want to know what coating curve you want - there are many possibilies.
That being said, these places have coating abilities:
-OptoSigma (Japanese, but I know they have a whole specific coating shop in California)
-Edmund Optics (NY)
-ThorLabs (NJ)
-REO Optics (CO) _________________

In the UK, I think the well-known Leica repairer and restorer Malcolm Taylor (Upper Lye Farm, Aymestrey, Leominster, Herefordshire, HR6 9SZ UK Tel 01568 770542) is still able to do recoating, although I don't know whether he can do multi-layer coatings. He has no website or published email address but in my experience is very helpful if you telephone him and he has a reputation for doing good work. He isn't cheap but the lenses he serviced for me last year were done well and sent back quickly. Might be worth trying if anyone has a top class lens that needs restoring. _________________ Stephen

I've heard Vasiline makes an interesting coating.
Seriously, there is a spray-can product. Just lay bare element on old newspaper & spray on coating. Each coat adds x microns -- calculate beforehand how many coats are needed to produce coatings for wavelengths desired. Multiple coatings are separated by a special sealing coat. Just kidding.
How about local University lab? I once got some quartz crystal matrix that had been in chamber used to prepare specimens for electronic scanning microscope -- coated it with 1-atom thick of purest gold, making crystal a beautiful blue color(!). _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

The where to get coatings question has been answered in several threads here at MFlenses! Search...
Iirc our HK friends know of places, some on the main land.
I wonder, for example, if somebody like Edmund Scientific Company would accept a batch of lens elements from MFlense members; as many elements as will fit in chamber -- cost savings... That, of course, will work only if machine will different element sizes at once...I'm not sure. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮

I specify optical filters as part of my job, so I specify coatings as well.
Because of this I know a bunch of coating companys, but mainly those for higher volume.
There it is usual to make special jigs to have the glass on it, so this is not possible for our needs with many different sizes. Don´t know how jigs with variable diameter would look like, and how few lenses it could hold on one coating run.
Most companies have a Broad-Band Anti-Reflection (BBAR) like coating for visual transmission. But without knowing the material of the glass it could be quite risky. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html
