Thin PMMA Fresnel Lens Sheet | 5 Inch Front Projection Optic | 160mm Focal Length for Display Panel Integration


Shandong Yuying Optical Instrument Co., Ltd, with 30+ years in Fresnel optics and ISO9001/ROHS/REACH certifications, delivers precise in-house manufactured optical solutions to global display equipment makers.


This 5-inch PMMA Fresnel lens sheet is engineered for front projection integration, combining a thin optical structure with a 160mm focal length for display panel applications.


  • Reducing optical module thickness is important in compact display engineering.
  • Thin Fresnel structures provide directional light control with minimal material usage.


Why use a thin Fresnel lens sheet in display systems?
A thin Fresnel lens sheet reduces overall module thickness while maintaining effective light direction control in projection-based displays.

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 is the advantage of a thin Fresnel lens sheet?
A: It helps reduce module thickness while preserving optical functionality.

Q2: Why is PMMA commonly used in Fresnel optics?
A: PMMA offers stable transmission and suitable optical processing characteristics.

Q3: What systems use long focal Fresnel sheets?
A: They are often used in projection and display integration assemblies.

Q4: Can the lens dimensions be customized?
A: Yes, optical and structural specifications can be developed for specific systems.




Advantages

Optical Features:

  • Installed at the front optical stage to organize projected light pathways
  • Thin-sheet structure supports compact display panel integration

  • Electronic display manufacturing systems

Manufacturing Advantages:

  • Specialized Fresnel lens fabrication capability
  • Independent mold engineering and optical replication
  • Consistent groove precision across production batches
  • OEM and customized optical 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.
