swarobright and non swarobright-what are the differences?

Hello, I am very curious what are the differences between swarobright and non swarobright optics. Is this difference visible in brightness only, or also in the clearness, clarity, sharpness and resolution?
I have recently found on international site two slc 7x42b one swarobright from 2002 (written on the box) and one non swarobright from 2001 with box with no swarobright written on it and I am interested in understanding what will be the difference in image between the two bins and if the price difference worth it.

Swarobright is the name Swarovski gives for the coatings on their roof prism binoculars. I believe they started using that name around 1999 but I could be wrong. The coatings on the prisms of their current series of binoculars are di-electric which are bright. I don't know what type of coatings they used back in 2001 and 2001.

Many binoculars were using silver coated prisms or the less bright aluminized coated prisms before the introduction of di-electric prisms. The differences in brightness between these coatings are readily visible.

You should look through any older binocular before you purchase it because many of them will show a yellow color caste to the view.

Here is a link discussing the abbreviations and the coatings on Swarovski binoculars.

Swarobright coatings yielded a slightly higher light transmission and a better color reproduction. Altogether it resulted in a slightly brighter image as the binoculars without Swarobright coatings.

This from 2001 has purple coatings, and there is no swarobright written on the box, does this mean that it will be with yellow cast and dimmer image?

I couldn't tell you that.

Remember that the 2001 SLC is 16 years old and lots of factors involving its use could have an effect on its brightness. It might need a professional cleaning by Swarovski in order to bring it back to par; the nature of its coatings not withstanding.

I wouldn't put too much stock on what was not written on the box about its coatings. More important is the instruction manual that comes with the SLCs which has information about Swarovski's coatings like Swarobright and Swarotop. You can find the date the manual was printed at the bottom of the page showing the technical data for it. For instance the one that came with my 2006 SLC 7x42 B was printed in 02/2006.

Some errors on that website, for example when talking about the EL

"field flattener lenses made with fluoride"

On the WEBsite of House of Outdoor I published an overview of the
'History and quality development of Swarovski Optik" and I have included an example of the effect of Swarobright coatings on light transmission/brightness in 8x30 SLC binoculars of different production years and without and with Swarobright coatings. The powerpoint is up-to-date to this year, so it includes the BTX binocular eyepiece for the modular ATX telescopes.

Gijs,

Great article!

I have an undated slide set entitled: "1935‐2011 From optical workshop to outstanding optical company." If there is an updated one in English would you mind posting the link or attaching the PDF file?

Thanks,
Ed

Ah, Gijs and Ed both together, Great.

I defer to my stroke concerning my forgetting of names of people I have known for a long time and it happens, again.

What was the last name of Zeiss' Walter _________. I believe he was either an engineer or a very colorful repair manager who retired about 15 years ago. I was working on my memoir and realized I could remember his name. But then, there was a time, today, when I couldn't remember my next door neighbor's name. He was my old ... bishop!

Like Mark Twain, it seems I am heading for that glorious time when the only things I will remember are
those that DIDN'T happen. From the standpoint of understanding mortal discrepancy, it is fascinating. From the standpoint of being the victim ... not so much.

Bill ... I think

Please answer by email.

Very nice reference article. (Of course, there are one or two small points ... and you might wish to update the file name ...)

Good job!

Ed

Gijs,

I was just being cute. The file name on the newest .pdf is "1935-2011 Swarovski Optik, Austria." So I changed my copy to read "1935-2017 Swarovski Optik, Austria."

Sorry to be a nudnik.
Ed

The first slide gives the proper content up to 2017 and, since the lecture was in 2011, it shows my crystal bol capabilities...in 2011.
