Robust optomechanics and optics on submounts

By utilizing flux-free soldering and CTE-matched submounts, our optomechanical assemblies enable low-stress mounting of optical components, ensuring long-term stability and high optical quality. This approach is particularly suited for deformation-sensitive elements, such as thin optical plates where wavefront planarity must be preserved. Additionally, the soldered, adhesive-free interfaces offer minimal outgassing, making them ideal for UV applications and contamination-sensitive environments. Our modular design allows for straightforward adaptation to different optic sizes and geometries.

High precision flexure mirror mounts with soldered CTE-matched optic interface

Our SFM mirror mounts feature monolithic bodies with optics soldered via CTE-matched submounts for maximum mechanical and thermal stability. The flux-free soldering process ensures stress-free, long-term reliable bonding without adhesives. This design enables robust, vibration-resistant alignment – ideal for high-stability beam delivery in demanding environments.

• Excellent pointing stability over changing conditions (Very low angle change (<20μrad in both axis) after multiple ΔT=60K temperature cycles

• Optical component soldered on CTE-matched submount to reduce thermomechanical stress

• Ultra compact design; minimal footprint

• Vacuum compatible

• Easily adaptable to different mirror dimensions

Optical components for machine-assisted assembly

Our active alignment technology enables us to achieve repeatable, consistent positioning of optical components in a molten solder interface. Local remelting using integrated heaters allows us to fix optical elements permanently and, stress-free fixation – without raditional mounts. The result: compact, robust, and precisely aligned optical systems.
