Package/Lens Component – Computer, Electronic and Optical Product Manufacturing

Component Specifications

Definition

A hermetic or non-hermetic optical package containing an infrared LED or laser diode chip, wire bonds, and a precision-molded lens that shapes the emitted infrared radiation beam. The package provides mechanical protection, thermal management, electrical connections, and optical control for the emitter.

Working Principle

The package encapsulates the semiconductor die in a protective housing while the integrated lens (typically molded from optical-grade plastic or glass) collimates, focuses, or diffuses the emitted infrared light through refraction and total internal reflection principles. The lens geometry determines the emission angle, intensity distribution, and optical efficiency.

Materials

Lens: Optical-grade polycarbonate, PMMA, or glass with IR-transmissive coatings. Housing: Thermoplastic (PBT, PCT) or ceramic (Al2O3) with metal leadframes (Alloy 42, copper). Seal: Epoxy resin or glass frit for hermetic packages. Die attach: Silver epoxy or solder.

Frequently Asked Questions

What is the difference between hermetic and non-hermetic packages for IR emitters?

Hermetic packages use glass or ceramic seals to prevent moisture and gas ingress, ensuring long-term reliability in harsh environments. Non-hermetic packages use epoxy resins and are cost-effective for commercial applications with controlled conditions.

How does lens geometry affect IR emitter performance?

Lens curvature and surface finish determine the emission pattern: spherical lenses provide wide angles, aspheric lenses collimate beams for longer distances, and diffuser lenses create uniform illumination. Precise molding ensures consistent optical characteristics.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
