ABSTRACT:
An ocular mounting assembly for adjustably mounting a pair of ocular devices, such as telemicroscopic loupes, to an eyeglass frame or head mount with linear and rotational adjustments, but with view angle being permanently preset in accordance with working distance. The ocular mounting assembly includes an adjustable ocular support assembly and an adjustable clamp assembly rotatably attached to the ocular support assembly. The ocular mounting assembly includes a housing and two slidable mounting arms to which the ocular devices are attached, the transverse cross-sectional shape of the housing interior and mounting arms being such that substantially all of the volume of the housing interior is consumed apart from close tolerances to facilitate the sliding motion, thus resulting in a structure which cooperates to assist in providing a substantially rigid assembly. The adjustable clamp assembly provides height and view angle adjustment of the ocular devices and allows the ocular devices to be flipped up out of the way when not needed. The height adjustment in conjunction with the view angle adjustment allows the line of sight to be adjusted while the ocular devices are positioned close to the eye or eyeglass lens.
