Holmarc’s goniometers use rolling contact guides with balls rolling on precision curved ‘V’ grooves for friction less and stick-slip free movements. Pre-loading of the ball guides ensure play less positioning and long term stability. Drive is achieved by a worm and gear mechanism. Graduations are marked on one side of the stage for measurements and repeatable positioning. Construction material of the goniometer is chosen as aluminium alloy for keeping the self weight of the device as minimum as possible. Black anodized finish is given to make the goniometer optics lab compatible.
