  • KINEMATIC OPTICAL DEVICE MOUNT
    Publication number: 20130293964
    Abstract: An optical mount is used for mounting an optical element, such as a beam splitter or a mirror, to a housing. The optical mount includes a pair of optical element retainer clamps that secure a first side of the optical element at respective first securement points on one of the major surfaces of the optical element, and also engage a first edge. A whiffletree retainer clamp secures a second side of the optical element at a second securement point on the one of its major surfaces. The whiffletree retainer clamp couples a whiffletree retainer to the housing, with the whiffletree retainer engaging a second edge along the second side of the device. The whiffletree retainer is positionally adjustable, for example able to pivot. Pivot pads may be used in at least some of the engagements to secure the optical element. The pivot pads may be segments of ball bearings.
