I am unsure if the retaining ring will fit securely behind the filter, as the filter's 6mm thickness exactly matches the maximum depth of the mount.

Hi Alper. You are right. A 6mm thick filter will not hold in this adapter. Sorry. Raf.

Retaining ring is included?

Hi Dan. No, sorry. Thorlabs has these retaining rings much cheaper than we can make them. Raf.
