Which model Omega is this?

It can be used to hold a red filter turning the enlarger into a safe light for black & white film or it can be used to hold contrast filters.

I have the red filter swing arm, took it off as I no long have any paper that is red filter safe, all OC. The arm in the picture is not a red filter, has a screen in it. Never seen one with a screen, might be DYI?

The photo in post #23, and again in post #24, appears to show a collection of parts for Omega B22 or B66 enlargers. Most of the B22 accessories also fit the similar B66. The part with the screen is likely the Portrait Diffusion Grid. It was sold for various models, such as the B22, B66, DII, D2, etc., each with a specific model number depending on the Omega enlarger for which it was intended.

We’re fortunate to have good source of data for these enlargers, components, and accessories available on the KHB Photografix site in Welland, Ontario.

OC filter safe papers are all red filter safe.
Papers that require a red filter are not safe to use with an OC filter safelight.
Traditionally, we preferred OC filter safe papers because the human eye is a bit more sensitive to the light from an OC filter safelight - things appear to be more fully illuminated under that light than under a red safelight.
But the advent of red led sources has made it possible to achieve higher levels of red light, without causing problems with either type of paper.
For paper designed for OC safelight, I'm using a wonderfully bright and easy to work under LED rope light safelight now, that has passed the Kodak Safelight test, so I am very happy.

I've not the diffusion screen, wonder how well it works.

I have one, though I only used it once or twice and that was several years ago. It did soften the image somewhat, but took a bit to dial in. If I remember correctly, I used it for around 50% - 75% of my total exposure time.

I also have the same thing with a red filter instead of the screen. I know there's a purpose for it but don't have a clear understanding of its intended function.

BTW, the enlarger in question is the D2V. I have two of them and really like them. I use them for all formats 16mm up to 4x5.

You move it into place over the paper, then turn on the enlarger, use the red image to position something like a dodging or burning tool and then remove the red filter to start the exposure.

I will have to test my under enlarger red filter to see if with age it is still safe. Last red light paper I used was Salvich, although still in production what with sanctions, not imported to the U.S.

Ah, I figured it was something simple. Thank you!
