Daheng Optics Optic Holders Stages Mount Structures Daheng Optics adopts different mechanical structures required by optical components for their positioning and alignment. Optical components have a variety of shapes and forms that needed to be held in position in optical systems; of their positions are required. Many mechanism and mechanical structures are implemented into the optic mounts and holders’ series, GCM series. The detailed descriptions of the structures are explained below. Retaining Ring This is the simplest and commonlyused mount structure for holding optical components. A retainer...

Optic Holders Self-Centering As its name indicates, this type of mount overcomes the eccentric problem in the retainer ring structure. The self-centering structure has three spring-loaded jaws that move along the same circular track to ensure its concentricity. This type of holders is ideal for holding optic components that are round and cylindrical in shape and requiring reliable axial positioning. Another advantage is that It can maintain the position of the optical axis even when lenses with different diameters are put in. lt has a sufficient diameter space to load and unload lenses, particularly in...

Daheng Optics Optic Holders Kinematic Mounts A mount is said to be kinematic when the number of degrees of freedom (axes of free motion) and the number physical constraints applied are six in total. This is equivalent to saying that any physical constraints applied are independent (non-redundant). A kinematic optical mount therefore has six independent constraints. The most common type of kinematic mount is the "cone, groove and flat” mount schematically illustrated in the figure below. Considering the optic as being attached to the coordinate system of the three spheres and its corresponding mount...

Position Resolution It is the smallest difference in movements that can be discriminated. Typically fingertips are sensitive enough to distinguish Repeatability It is the error within which a given position can be reproduced. Unidirectional repeatability is measured by approaching a 0.5°~1°rotations of an adjustment screw, in some cases, is much less. Therefore, we define the position position from a single direction, hides errors caused by backlash effects. Bidirectional repeatability is measured by approaching a All dimensions are in mm unless otherwise specified. resolution as the angular...

Daheng Optics 00170 China Daheng Group. Inc. www.cdhcorp.com Optic HoldersGCM-04 Self-Centering Lens Holders The holders offer a reliable and self-centering mechanism for holding lenses or other round optical components. They are very useful when optics of variable diameters must be interchanged frequently and the height of the optical axis must be kept unchanged. They can be mounted on any post.
