ABSTRACT
Depending on the final application and further requirements, where pricing may play an important role, different approaches can be applied for mounting optical components and assembling optomechanical systems, respectively. Stacking is a well-established standard technique for the assembly of on-axis optomechanical systems including several single optical elements, for example, air-gapped achromatic doublets or triplets. Clamping is another standard technique for mounting optical components. Mounting of optomechanical systems by glass-metal soldering is a comparatively novel technique. Optical components can furthermore be mounted by gluing or clamping with tension springs or bent latches. Inappropriate tolerances and form deviations of the used mechanical elements, such as tilted bearing surfaces or deviations in diameter, may lead to tilt and decenter of mounted optical elements. Such position or distance errors may have a severe impact on the imaging quality of optomechanical systems. The contour accuracy and precision of mounts, spacer rings, and tubes is thus of essential importance.
