Adapters allow to mount objectives with different threading, for example the nosepiece has RMS (20.2 mm) threading but you would like to use an objective with Mitutoyo (26 mm) threads, see image.
Since most current objectives are Infinity designs the additional length of the adapter does not create a problem.
Most objectives with Mitutoyo threading (26 mm x 36tpi) are much larger in diameter than DIN objectives and it will often not be possible to fit more than 2 objectives on much smaller diameter nosepieces with RMS threading.
Parfocal length of Mitutoyo style objectives is 95 mm versus 45 mm for DIN objectives. Our adapter adds another 9 mm. On most scopes for DN objectives the stage adjustment will not allow for additional 59 mm.
