With the widespread adoption of LED technology, Linear Fresnel Lenses are gaining increasing popularity across various industries, especially in lighting and solar thermal applications.

A Linear Fresnel Lens is a specialized type of Fresnel lens composed of a series of prism-like ridges. These ridges vary in width and tilt angle—becoming wider and steeper towards the center—enabling the lens to focus light into a line, rather than a point. This unique linear focusing capability distinguishes it from conventional point-focusing Fresnel lenses.


Principle & Advantages

Under sunlight, the linear Fresnel lens focuses light into a narrow line, making it ideal for CSP (Concentrating Solar Power) systems. It concentrates sunlight onto a heat transfer tube, which transfers thermal energy to a heat storage system, ultimately enabling solar power generation.


Main Uses

  • Linear solar heat collection
  • Optical viewfinder systems
  • Barcode scanning and recognition





Advantages

Compared to traditional convex lenses, Linear Fresnel Lenses offer the following advantages:

  • Ultra-thin and lightweight design
  • Available in large sizes and customizable shapes
  • Excellent light transmittance and focusing performance
  • Cost-effective and easy to handle
