Lens Mount / Housing for Collimating Lens Assembly

Product Specifications

Technical details and manufacturing context for Lens Mount / Housing

Definition

The lens mount/housing is the mechanical framework of a collimating lens that provides precise alignment, stable fixation, and environmental protection for the optical elements (lenses). It ensures the optical axis remains fixed and maintains the required spacing between lens elements for proper collimation of light beams. The mount/housing mechanically constrains the optical elements using precisely machined surfaces, threads, or retention mechanisms. It maintains dimensional stability against thermal expansion, vibration, and mechanical stress to preserve optical alignment. The housing may also incorporate features for heat dissipation, sealing against contaminants, and mounting interfaces to larger optical systems. Typical materials include aluminum alloy, stainless steel, and engineering plastic. Key parameters include outer diameter (25–60 mm), inner diameter (18–50 mm), height (10–30 mm), wall thickness (1.5–3.0 mm), thread pitch (0.5–1.0 mm, ISO 68-1), surface flatness (0.01–0.05 mm, ISO 1101), concentricity (0.02–0.10 mm, ISO 1101), surface roughness (0.4–1.6 μm Ra, ISO 4287), operating temperature (-40–85 °C), material grade (6061-T6, ASTM B221), weight (10–50 g), and IP rating (IP54–IP65, IEC 60529). These values are reference ranges; verify model-specific specifications with the legal manufacturer or supplier. The housing is a component used in optical systems, and its selection depends on the lens barrel diameter, required rigidity, and environmental conditions. Proper installation and maintenance are essential to preserve optical performance.

Working Principle

The mount/housing mechanically constrains the optical elements using precisely machined surfaces, threads, or retention mechanisms. It maintains dimensional stability against thermal expansion, vibration, and mechanical stress to preserve optical alignment. The housing may also incorporate features for heat dissipation, sealing against contaminants, and mounting interfaces to larger optical systems.
