Standard DIN nosepieces have 4 or 5 positions.
Iimage below shows the quintuple nosepiece coming with the FU1000 focus block, outside diameter 71 mm..
Quadruple RMS threaded nosepiece with centering, outside diameter 83 mm.. Because of larger diameter all positions can be filled with Mitutoyo style objectives.
Option with larger nosepiece, outside diameter 110 mm, and Mitutoyo threading (26 mm), allows to install up to 5 Mitutoyo or workalike objectives.
You can use all positions only when using DIN form factor objectives . Because of much larger diameter only 2 positions can be used with Mitutoyo or workalike objectives
Above image shows installation of Mitutoyo workalike objectives using our adapters.
Red arrows point to detachable centering keys. .
You can use original Mitutoyo or lower cost workalike objectives, for even more savings.
Objectives with RMS threading can be used directly. That includes all DIN objectives from Meiji Techno and numerous other suppliers. Also, some of our Mitutoyo workalike objectives come with DIN threading and fit right in after removing the supplied 26 mm adapter.
With the help of special RMS to Mitutoyo adapters you can use original Mitutoyo or workalike objectives with 26 mm threads.
DIN objectives can be used with a Mitutoyo to RMS adapter, see bottom of page.
When mixing DIN and Mitutoyo objectives you will need a special extension adapter to keep objectives parfocal.
