Lens Kit for 23C Enlargers

This 50mm f/3.5 Beslar lens kit is built for the 23C Series enlargers. It supplies the taking lens, a 39mm front lensboard with pilot light, and a 35mm negative carrier in one package. The kit suits darkroom workers who print 35mm negatives and want matched components.

Check Your Enlarger Series

Verify that your enlarger is a 23C Series model before ordering. The 39mm lensboard and the 35mm carrier are made for the 23 and 45 Series mount pattern and the 23C carrier slot respectively. A different series or a non-Beseler chassis will not accept these parts.

What the Bundled Parts Provide

The included 39mm front lensboard (#8021) mounts the Beslar lens (#8670) and adds a pilot light for composing under safelight. The 35mm negative carrier (#8053) holds standard 35mm strips flat during exposure. Together they replace separate purchases of lensboard, lens and carrier.

Questions about this item

What comes in the Beseler 50mm f/3.5 Beslar Lens Kit #9170 and what must I buy separately?

The kit includes the 50mm f/3.5 Beslar lens #8670 with cap and jam nut, a 39mm front lensboard #8021 with pilot light, and a 35mm negative carrier #8053 for 23C enlargers. You will need a compatible 23C or 45 series enlarger body and darkroom supplies such as paper and chemicals.

Which version of the 50mm f/3.5 Beslar kit should I choose for my 23C enlarger?

This #9170 kit is built for 23C series enlargers. It supplies the correct 39mm lensboard #8021 and the 35mm carrier #8053 that fit that series, so no other version is required.

What does the f/3.5 aperture mean when I use the 50mm Beslar lens on a 23C enlarger?

At f/3.5 the 50mm lens passes a generous amount of light for bright viewing and reasonable exposure times, while still delivering the sharpness needed for 35mm negatives on a 23C enlarger.
