Angular tilt fixture
An adjustable stand that holds and tilts an optical assembly at set angles over a sample on an optics bench.
Hold an optical assembly at a precise, repeatable angle over a sample and then adjust that angle without re-aligning everything else on the bench.
An A-frame stand carries a mounting plate on a geared tilt joint. The gear segment sets the angle and locking knobs hold it. The optics mount on top of the plate and the clamp jaws hang below, so the whole assembly tilts as one piece about a single axis.
