Projector Fresnel Lenses | 7 Inch Front PMMA Lens | 200mm Focal Length for LED & LCD Projection Systems


Shandong Yuying Optical: 30+ years in Fresnel optics, ISO-certified, providing precise optical solutions worldwide.


This 7-inch front Fresnel lens is engineered for high-precision LED and LCD projector systems, providing optimized light focusing and enhanced image clarity. Its PMMA optical substrate ensures lightweight integration while maintaining stable transmission across large-screen projection setups. Designed with a 200mm focal length and fine 0.3mm groove pitch, it delivers uniform illumination and minimal beam divergence, making it ideal for home cinema, educational, and commercial projection applications.


Front Fresnel lenses optimize light focusing for LED and LCD projectors.
High focal PMMA lenses enable precise projection and stable image quality.

Q1: What is the role of a front Fresnel lens in projectors?
A1: It focuses LED/LCD light, improving image clarity and reducing beam divergence.

Q2: Why use PMMA for this lens?
A2: PMMA provides lightweight structure with stable optical transmission.

Q3: What is the benefit of a 200mm focal length?
A3: It enables controlled light propagation for large-screen projection.

Q4: Can specifications be customized?
A4: Yes, dimensions, focal length, and groove pitch can be tailored.




Advantages

Key Optical Features:

  • Designed for front placement in projector systems to focus LED/LCD light efficiently
  • High focal length ensures long-distance light collimation and minimized beam divergence
  • Fresnel groove matrix improves light uniformity and image clarity
  • PMMA substrate offers lightweight integration while maintaining optical stability
  • Suitable for high-brightness and large-screen projection applications

Applications:

  • LED & LCD projectors
  • Home cinema and educational projectors
  • Commercial display and large-screen projection systems
  • Imaging modules for optical integration

Manufacturing Advantages:

  • 30+ years of Fresnel lens production experience
  • ISO9001, ROHS, REACH certified
  • In-house tooling and precision molding for consistent groove replication

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.
