Component Specifications

Definition
A reflector is a critical optical component within infrared emitter arrays, designed to efficiently redirect, collimate, or focus infrared radiation emitted by IR sources (such as LEDs or filaments) toward a target area. It optimizes energy distribution, enhances system efficiency by minimizing losses, and ensures uniform irradiation patterns in applications like industrial heating, drying, curing, and non-contact temperature sensing systems.
Working Principle
Operates on the principle of specular or diffuse reflection, where infrared radiation incident on the reflector's surface is redirected according to its geometry (e.g., parabolic, elliptical, or flat) and surface coating. This manipulation of light paths increases irradiance on the target, improves thermal uniformity, and maximizes energy utilization from the emitter sources.
Materials
Typically made from aluminum alloys (e.g., 6061-T6) for lightweight durability and high thermal conductivity, with a polished or anodized surface. High-temperature applications may use stainless steel or ceramic substrates. The reflective surface is often coated with gold, silver, or enhanced aluminum via physical vapor deposition (PVD) to achieve >90% reflectivity in the infrared spectrum (e.g., 700 nm to 14 µm).
Technical Parameters
  • Geometry Parabolic, elliptical, or custom
  • Mounting Screw or clip-based
  • Reflectivity >90% in IR spectrum
  • Surface Finish <0.8 µm Ra (polished)
  • Coating Thickness 0.1–2 µm
  • Thermal Conductivity >150 W/m·K
  • Operating Temperature -40°C to 300°C
Standards
ISO 10110, DIN 3140
