This is a single piece square 50 mm optical axis fixed seat with an aluminum alloy wire base, circular flange support, and guide shaft support. It provides a stable, precise optical axis and robust mounting in compact assemblies. The 50 mm square optical axis fixed seat consolidates multiple functions in one unit, reducing the need for separate parts and simplifying alignment tasks. Key benefits Precise optical axis alignment: the fixed seat provides a stable reference for the optical axis, helping maintain alignment over time. Rigid, lightweight construction: aluminum alloy offers strength with low weight for easy installation and reduced vibration. Integrated mounting features: circular flange support and guide shaft support are included in a single unit, simplifying assembly and improving rigidity. Spacesaving and easy integration: the compact 50 mm square footprint fits in tight spaces and pairs with standard 50 mm axis configurations. One piece design: eliminates the need to assemble multiple parts and reduces potential misalignment during installation. Key attributes Size: 50 mm square optical axis fixed seat Material: aluminum alloy base Features: optical axis fixed seat, aluminum alloy wire base, circular flange support, guide shaft support Configuration: 1 piece unit Compatibility: designed for 50 mm optical axis setups and related components requiring a fixed axis seat and guide shaft support Performance: provides rigid mounting with lightweight construction due to aluminum alloy Use cases Optical alignment fixture: provides a fixed optical axis reference with a circular flange for attaching adapters and a guide shaft support for stable guidance. Compact linear motion or positioning system: holds the optical axis securely while guiding motion with the guide shaft support, improving alignment stability in tight spaces. Experimental or bench setups: enables mounting of optical components and adapters on a stable fixed seat, with the circular flange support and guide shaft support aiding reliable alignment in laser, imaging, or sensing configurations.
