An adjustable optical device including an optical element, a housing having an adjusting post fixed thereto, the optical element mounted to the housing, the housing adjusting post having a plane of movement, and an adjustment mechanism, the housing flexibly connected to the adjustment mechanism, the adjustment mechanism comprising a moving adjusting member in sliding engagement with the housing adjusting post, one of the adjusting member and the housing adjusting post comprising a wedge. The housing adjusting post is urged into movement in its plane of movement in response to relative movement between the adjusting member and the adjusting post, whereby the orientation of the optical element relative to the adjusting mechanism is adjusted by movement of the moving adjusting member.

Precisely adjustable optical device having vibration and temperature stability

A duplex bearing mount including at least one duplex bearing having an inner race and an outer race, the inner race disposed within the outer race and being rotatable relative to the outer race about an axis, the inner race having substantially no relative movement relative to the outer race in at least one direction along the axis, the inner and outer races each having first and second axial faces which are respectively located at the same axial end of the duplex bearing. The duplex bearing is radially supported by a housing, and a shaft extends through the inner race, the shaft radially and axially supported by the inner race. A first retainer is connected to the housing and engages the first axial surface of a bearing race, the movement of which race in a first direction along the axis being constrained by the first retainer. A second, resilient retainer is connected to the housing or the shaft and is deflected through engagement with the second axial face of a bearing race, the movement of which race in a second direction along the axis, opposite to the first direction, being constrained by the deflected second retainer. The bearing is preloaded by its being clamped between the first and second retainers, and the second retainer forms at least a portion of a spring having the characteristic of a substantially constant force value correlating to a range of various deflection values, whereby the preload of the bearing is substantially unaffected by variations in the deflection of the second retainer.

Compact, precision duplex bearing mount for high vibration environments
