The Oasis OAG features an outer thread of M28.5x0.6 at the front of the prism mounting post, ingeniously enabling the use of the helical focuser to adjust the prism's position.

The dial is marked with six major divisions: 0, 1, 2, 3, 4, and 5. Thus, for every major division the dial rotates, the prism post moves by 1mm. Each major division is further subdivided into 20 minor divisions, providing a fine adjustment precision of 0.05mm per minor division.\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003eBefore starting adjustment, set the helical focuser to its minimum focusing travel.
