B+W Equivalencies and B+W Catalog Links

[Cadmium]

---

EDITOR'S NOTE: The following discussion of B+W and Schott equivalencies and the B+W catalog links began in my Amaryllis 099/550 topic. But for better searchability, I've split the discussion off into its own topic.

---

 

 

B+W 099 is uncoated Schott OG550 filter glass.

B+W 040 is coated Schott OG550 filter glass.

 

B+W Infrared filters (no coatings): 092 (Schott RG695), 093 (RG830), 099 (OG550).

B+W Black & White filters (available with coatings): 021 (Schott GG455), 022 (GG495), 023 (OG530), 040 (OG550), 041 (OG570), 090 (OG590), 091 (RG630).

All are made of Schott filter glass.

 

B+W 099, B+W 040, and Schott OG550 are all the same filter glass, are all orange longpass IR filters with 50% transmission at 550nm. Only the B+W 040 is coated.

 

According to B+W's catalog/handbook (page 62), B+W 099 is not coated, the B+W 040 has coatings.

Thankee, Cadmium !!!

So my raw colour fotos "proved" the equivalence of 550 and 099 that we already knew. :lol:

 

I wanted to do one of my spectralon studies for those two filters also. But then I realized that instead I had better tackle the broken links in the Filters Sticky. (Ugh!!!!!)

 

Side Note: I just searched everywhere for the B+W catalogue on the B+W pages and have not yet found it. Strange, huh??

[Cadmium]

Andrea, I noticed that the B+W link you had in the sticky is a bad link now, or I would have used that instead of the link I used above.

 

I can't find 099 anywhere. Even B+W (Schneider Kreuznach) doesn't list the 099, so it must be discontinued.

Only 092 and 093:

[Cadmium]

Here is their new catalog. See page 38 for coatings. The 092 and 093 infrared are not available with coatings. The Black & White filters are available with coatings.

So it looks like to me, if anyone wants at 099 new you can't get those now, only the 040, unless you get a Schott OG550, which would be like the 099.

 

At the link below, click on "Photo Optics - Procures".

The have three filter PDF downloads, I was looking at the first top one.

These should be used for reference now, given that some of the info has changed from the catalog I have been using, like the disappearance of the 099 filter from their list of products.

Looks like the difference between the three filter catalogs is this:

1) 1st PDF (top) = full round filter catalog.

2) 2nd PDF = short catalog version.

3) 3rd PDF = square filter catalog.

 

Here is direct link to the top PDF, see page 38 for coating guide.

B+W offers the following Schott longpass filters:

 

Schott GG395 = none

Schott GG400 = B+W 415 -

Schott GG420 = none (equivalent to B+W 420 - ,apparently discontinued)

Schott GG435 = none

Schott GG455 = none (equivalent to B+W 021 - ,apparently discontinued)

Schott GG475 = none

Schott GG495 = B+W 022 +

Schott OG515 = none

Schott OG530 = none

Schott OG550 = B+W 040 + (also equivalent to B+W 099 - ,discontinued)

Schott OG570 = none

Schott OG590 = B+W 090 +

Schott RG610 = none

Schott RG630 = B+W 091 +

Schott RG645 = none

Schott RG665 = none

Schott RG695 = B+W 092 -

Schott RG715 = none

Schott RG9 = none

Schott RG780 = none

Schott RG830 = B+W 093 -

Schott RG850 = none

Schott RG1000 = none

 

- = No coating

+ = E or MRC coating

B+W longpass filters listed in the new B+W catalog are shown in black as the Schott name on the graph below.

Cadmium,

So are the B+W 021 equivalent to a GG455, B+W 415, equivalent to GG400, and B+W 420 equivalent to GG420, officially discontinued?

[Cadmium]

David,

The B+W 415 = Schott GG400, and it remains listed in the new B+W catalog linked to above. I missed that one, thanks.

I don't see the B+W 420 listed in the new catalog.

I don't see the B+W 021 listed in the new catalog.

They are listed in the old catalog/handbook, but those two may no longer be available. Let me know if I need to correct that.

I have added a graph above comparing all longpass filters offered by Schott to all longpass filters listed in the new B+W catalog.

[dabateman]

B&H has the B+W 415 in stock, but the 420 and 021 as discontinued. So they may be gone.

But B&H if doesn't have stock will mark any product as discontinued even if not, just because they do have instock supply. Thus, why I asked. You seem to be more filter informed than most.

[Cadmium]

I am only going by the info listed in the new catalog.

https://schneiderkreuznach.com/download_file/force/1956/1085

See page 38 for list of filters and coatings.

[dabateman]

I wonder if the 010 is the replacement or same as the 415?

You can see its transmission on page 12 and it comes with all the fancy new coatings. Whereas now they list the 415 as not coated.

Yes it does look like they have simplified their filters. As in digital fewer people use filters.

I am surprised to see series 7 and 8 filters listed in the table though. Not sure when a lens was last made with a series front element. Just like Bay 60 filters, I thought the series system was dead.

The filters discussion above contain excellent information, but has nothing directly to do with this therad's Amaryllis.

I suggest that the essential parts gets it's own topic, with a descriptive title to make it easier to find later.

[Andrea B.]

That is probably a good idea, Ulf.

I'll split off the B+W filter catalogue discussion.

 

BTW, I am now working on repairing the broken links in the Filters Sticky. Websites have been switching to https and that broke quite a few links. It is tedious work, but I've made a bit of progress.

415 is the same as GG400, always has been, compare old and new catalogs. It is still in the new catalog.

010 transmits down to about 350nm, so that is not GG400. 010 is nothing new, it is in the new and old catalog.

 

Old:

I was originally responding to several points that Andrea made or asked in her original topic post.

https://www.ultravioletphotography.com/content/index.php/topic/3631-amaryllis-in-the-500s-with-bw-099-and-schott-og550-and-others/page__view__findpost__p__31829

 

I was responding that,

1) 099 is 'not' coated (and no longer made).

2) found the new B+W catalog that Andrea was looking for.

Yes your correct. The scale is in 50s but 100 apart which first confused me. So the end is 350nm, not 400nm like I assumed.
