Fresnel Lens for Projector Manufacturer | 5 Inch Rear Projection PMMA Optic | 110mm Focal Length for Display Imaging Systems


Shandong Yuying Optical – 30+ years in precision Fresnel optics, ISO-certified, delivering reliable high-performance lenses to global display manufacturers.


This 5-inch rear projection Fresnel lens is engineered for projector manufacturing, supporting stable image transmission and efficient optical integration in display systems.



  • Projection image quality depends on stable optical transmission pathways.
  • Fresnel structures reduce optical thickness while maintaining directional light control.



Why are Fresnel lenses used in projector manufacturing?
Fresnel lenses help direct and stabilize projected light, improving image transmission efficiency while reducing optical structure thickness.


Customization Services

Yuying 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: Why use Fresnel lenses in projectors?
A: They help guide projected light while reducing overall optical thickness.

Q2: What is the benefit of rear projection placement?
A: It helps regulate image transmission at the final optical stage.

Q3: Why is PMMA suitable for projector optics?
A: PMMA offers lightweight structure and stable optical transmission.

Q4: Can the lens specifications be customized?
A: Yes, focal length, dimensions, and groove parameters can be adjusted.




Advantages


Optical Performance:

  • Installed at the rear optical stage to optimize projected image transmission
  • Designed to manage image field stability across projection surfaces
  • Fresnel groove structure supports directional light propagation with reduced optical loss
  • PMMA acrylic substrate provides lightweight optical integration for projector assemblies
  • Suitable for projection systems requiring balanced image output and stable transmission behavior

Application Scenarios:

  • LCD and LED projector assemblies
  • Imaging display modules
  • Projection visualization equipment
  • Digital display integration systems

Manufacturing Capability:

  • Dedicated Fresnel optics manufacturing facility
  • In-house tooling and optical replication process
  • Stable groove consistency across mass production
  • OEM and customized projector lens solutions 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.
