Single-piece anodized optical locator clamp with screws — aluminum alloy shaft stop collar / fixed ring, 18 x 32 x 10 mm. Provides a precise, repeatable mechanical stop and secure clamping for optical components along a shaft. Key benefits Precise, repeatable positioning: locates lenses, housings, or sensors reliably along a shaft to restore alignment quickly between setups. Secure, tool-tightened retention: threaded screws clamp the single-piece ring for stable, vibration-resistant holding. Corrosion-resistant and lightweight: anodized aluminum alloy gives durable surface protection and high stiffness without significant added mass. Space-efficient: compact 18 x 32 x 10 mm footprint fits tight optical benches and microassembly fixtures. Simple installation: includes mounting screws so the part can be fitted and adjusted immediately. Key attributes Material: aluminum alloy. Finish: anodized for wear and corrosion resistance. Size: 18 x 32 x 10 mm. Function: optical locator clamp combined with a shaft stop collar / fixed ring. Mounting: screws included for fast, secure attachment. Performance: lightweight yet sturdy, designed for repeatable alignment in precision optical workflows. What’s included 1 × single-piece anodized optical locator clamp (aluminum alloy shaft stop collar / fixed ring), size 18 x 32 x 10 mm. Mounting screws for installation. Applications and use cases Optical bench alignment: position and lock a small lens housing or sensor assembly at a repeatable location on a shaft during experiments or instrument setup. Position-limiting stop: act as a fixed shaft stop collar in linear or rotary stages to prevent overtravel and maintain a defined mechanical limit. Compact fixtures and jigs: integrate into tight microassembly or calibration rigs where a dependable locator and stop are required for repeatable measurements. Compatibility guidance Intended for standard optical assembly workflows that require a locator clamp combined with a fixed-ring shaft stop collar. Compatible with common shafts and mounting arrangements used in precision optical equipment and alignment fixtures; verify shaft diameter and screw interface match your hardware before installation. Notes Sold as a single unit; includes the mounting screws. Anodized finish improves resistance to wear and corrosion in typical laboratory and workshop environments.
