12mm adapter to match parfocal heights of DIN and RMS objectives, black

• Front side - RMS (0.8″ - 36 tpi) female thread
• Rear side - RMS (0.8″ - 36 tpi) male thread
• Max. diameter - 24 mm
• Distance between flanges - 12 mm

If you need to mix DIN (45mm parfocal height) and RMS (about 33mm parfocal height) objectives on the same turret, you can add these adapters to RMS objectives, so all your mounted objectives will have same 45mm parfocal height.

This way you will need just micro adjusting after switching from one objective to another.
