Thermal compensating optical component mount and related devices
A novel optical component mount is disclosed, which includes at least one first mount body with at least one adjustment member traversing through at least one adjustment member passage formed in the first mount body. At least one second mount body is configured with at least one component aperture formed therein and at least one insert receiver formed therein. The insert receiver is configured to receive at least one thermal compensating positioning insert positioned in the insert receiver. The coefficient of thermal expansion of the thermal compensating positioning insert is configured to be equal to the coefficient of thermal expansion of the adjustment member. At least one engaging body is positioned in the thermal compensating insert and engages the adjustment member. The engaging body is configured having a coefficient of thermal expansion less than the coefficient of thermal expansion of the thermal compensating positioning insert and the coefficient of thermal expansion of the adjustment member. At least one biasing system movably couples the second mount body to the first mount body. During use, the combinations of the coefficients of thermal expansion of the components described above, result in minimal changes in position of the optical component mount during changes in ambient temperature.
