LED Collimating Fresnel Lens for Projector | 5.8 Inch Front Optical Collimation Panel | 210mm Focal Length for LED Projection Modules


Shandong Yuying Optical Instrument Co., Ltd provides 30+ years of expertise in Fresnel optics, in-house precision manufacturing, and ISO9001/ROHS/REACH certified optical solutions for global display and projection systems.


This 5.8-inch Fresnel lens is designed for LED light collimation in projector systems, supporting controlled beam alignment and long-distance optical propagation.


  • LED light sources require beam collimation for efficient projection performance.
  • Collimated light improves directional stability in optical projection systems.


What is a collimating Fresnel lens used for in LED projectors?
A collimating Fresnel lens aligns diverging LED light into a more parallel beam, improving projection direction control and optical efficiency.

Customization Services

Yuying is 30+ years in Fresnel optical manufacturing, provides customized Fresnel lenses for projectors, tailored in terms of focal length, dimensions, and groove design.


  • Custom Fresnel lenses available in varied sizes, shapes and focal lengths
  • Optimized thread pitch/tooth profile: Enhances resolution, clarity and brightness
  • Eccentric condenser lens technology: Expands keystone correction range for optimal viewing in both desktop/ceiling installations
  • Front-rear lens configuration improves light utilization efficiency


Q1: What does collimation mean in projection optics?
A: Collimation refers to aligning light rays into a more parallel propagation path.

Q2: Why are collimating lenses important for LEDs?
A: LED light naturally spreads outward and requires optical guidance for efficient projection.

Q3: Why use a long focal Fresnel structure?
A: Longer focal designs help stabilize beam direction over extended optical distances.

Q4: Is this lens suitable for custom projector systems?
A: Yes, dimensions and optical parameters can be customized for different projector modules.




Advantages

Optical Characteristics:

  • Positioned before the projection stage to align emitted LED light paths
  • Designed for collimation applications requiring controlled beam propagation
  • Long focal configuration supports extended optical channel management
  • Fresnel ring geometry assists in reducing beam divergence across projection systems
  • PMMA optical material enables lightweight integration with stable transmission behavior

Application Scenarios:

  • LED projector modules
  • Optical collimation assemblies
  • Beam shaping systems
  • Projection light management equipment

Manufacturing Capability:

  • Specialized Fresnel optics production facility
  • Independent tooling and precision replication workflow
  • Stable groove profile consistency in large-scale manufacturing
  • OEM and custom optical engineering support available

Functions

Fresnel lenses perform beam collimation and focusing:

1. Convert point sources into parallel light, significantly enhancing edge brightness of display panels while eliminating sunspot effects and improving overall brightness uniformity
2. Typically used with other optical components (e.g. cylindrical lenses)
3. Removing collimation lenses causes substantial light loss through panels, resulting in noticeable hotspots and reduced edge brightness
4. On the reverse side of LCD screens, light must be converged from panels to projection lenses



Application Examples

  • Portable Projectors: Ultra-thin Fresnel lenses enable compact optical engines as small as the palm of your hand.
  • Rear-Projection TVs: Large-format Fresnel screens are used for light diffusion and viewing angle control.
  • 3LCD/DLP Projection Technology: Both rely on Fresnel lenses as key optical components for light collimation and concentration.
