Polycarbonate Injection Molded Lens Housing

Product Specifications

Technical details and manufacturing context for Polycarbonate Injection Molded Lens Housing

Definition

This precision injection molded component is designed to house and protect optical elements in industrial applications. It provides environmental sealing while maintaining optical clarity for light transmission or sensor operation. The housing serves as a critical interface component in B2B supply chains for lighting manufacturers, automotive suppliers, and industrial equipment producers. It enables modular assembly while protecting sensitive optical components from dust, moisture, and mechanical damage.

Typical materials include polycarbonate (PC) and optical-grade PMMA. Key parameters, which must be verified for the specific model, include wall thickness of 2.0–3.5 mm, light transmission of 88–92% at 550 nm (ASTM D1003), haze level of 0.5–1.5% (ASTM D1003), operating temperature range of -40 to 120 °C, flammability rating of V-2 to V-0 (UL 94), surface roughness of Ra 0.05–0.2 μm (ISO 4287), diameter of 20–100 mm, tensile strength of 60–70 MPa (ISO 527), Izod impact strength of 600–800 J/m (ISO 180), heat deflection temperature of 125–135 °C (ISO 75), water absorption of 0.15–0.25% (ISO 62), UV resistance of ≥1000 hours (ASTM G154), mold shrinkage of 0.5–0.7% (ISO 294-4), and density of 1.19–1.21 g/cm³ (ISO 1183).

These values are reference ranges for directory purposes; actual specifications depend on the application and must be confirmed with the legal manufacturer or supplier. The housing is not a finished product but a component that requires integration into a larger assembly. Buyers should verify dimensional compatibility, optical performance, and environmental sealing requirements for their specific use case.

Working Principle

The housing provides structural support and environmental protection for optical elements while allowing controlled light transmission through precision-molded optical surfaces. The injection molding process creates a rigid enclosure with integrated mounting features and optical windows. The material's transparency and surface finish determine light transmission and haze. Sealing features prevent ingress of dust and moisture, while the material's thermal and mechanical properties ensure stability across operating temperatures. The design must balance optical clarity with structural integrity, as wall thickness affects both light transmission and impact resistance.

Frequently Asked Questions

What materials are used for this lens housing?

The housing is typically made from polycarbonate (PC) or optical-grade PMMA. These materials offer transparency and impact resistance. The specific material grade should be confirmed with the supplier for your application.

What are the typical light transmission and haze values?

Light transmission is typically 88–92% at 550 nm, and haze is 0.5–1.5%, both measured per ASTM D1003. These values are reference ranges; actual performance depends on the specific design and material.

Can this housing withstand outdoor environments?

The housing has a UV resistance of ≥1000 hours per ASTM G154, indicating resistance to yellowing. However, long-term outdoor performance depends on the specific material and design. Verify with the manufacturer for your environmental conditions.

How do I verify that the housing meets my requirements?

Check the listed parameters such as wall thickness, operating temperature, and flammability rating against your needs. Always confirm model-specific values and standards with the legal manufacturer or supplier before procurement.
