Locating a B+W 099 IR filter

[Tony-S]

The Usual Suspects used to sell this filter but now it seems to be D/C. I need a similar filter in 52mm. Does anyone know the equivalent of this filter from other manufacturers that is still available today?

These guys say they have 'em. Good price at that.

i have a 099, but from what I remember when sourcing it is that the B+W orange filter is essentially the same. Maybe an extra coating on the 099.

 

[Paul Cunningham]

Actually there's a 62mm on the 'Bay right now, that's what I'd do.

I've got a 67mm that I use in place of an orange filter sometimes and it works about the same.

 

[Tony-S]

OK, thanks for the replies. I've ordered a #21 to see if that will do the job.

Do color infrared images look the same (or pretty close) to the B+W 099 with the #21 orange? I have a B+W 099 in 52mm, and need an equivalent in 77mm, since 099 has been discontinued.

Last I looked at Aerochrome, "minus blue" (Wratten 12) was the spec'd filter to use. The 099 and Wratten 21 filters might do something along the right lines, but I'd start with what the spec calls for and branch out from there if the look wasn't what I wanted.

I don't know. I ordered the filter for a DNA gel electrophoresis setup in my lab.

I have used the Wratten 12 and it leaves (no pun intended) vegetation somewhat purplish, where as with the B+W099, the vegetation is more reddish, which I like.

I didn't realize the original poster was using the filter for electrophoresis.

For color infrared use, anything from #12 yellow to orange will be ok. I wouldn't go too deep with the orange, though. The #16 orange is probably better than #21. Seems like the B+W 040 and 099 filters are closer to #16 light orange.
I have a comparison shot with #12, #16, #25 filters:

Thanks, mjork, that's great information! I appreciate it. Especially the recommendation of #16 orange over a #21 orange filter.

does anyone know where to find one/ have one for sale at the moment?
