Optical Fresnel Lens for LED 500mm Focal Length 470×260mm Large-Format Light-Field Shaping Optic


This PMMA LED Optical Fresnel Lens is developed for lighting systems that require controlled light-field shaping, directional output, and efficient optical integration. Its 500mm focal length and 0.5mm groove pitch provide a practical optical geometry for managing LED-generated light across extended working distances.

The rectangular format can be manufactured within 470×260mm, making the lens suitable for large-area LED luminaires and optical modules where available installation space follows a rectangular architecture.

Using optical-grade PMMA, the lens offers a lightweight alternative to conventional bulk optics while allowing Fresnel geometry to be incorporated into large-format lighting assemblies.


Customized Services

1. High precision: Tip Width (R) ≤ 0.005mm, with loop distance as small as 0.02mm.

2. Molds capacity: We can process lens molds ranging from as small as 1mm to as large as 2200mm in diameter, accommodating a wide variety of specifications.

Customer also Ask

What is an Optical Fresnel Lens for LED?
An Optical Fresnel Lens for LED is a lightweight optical element that uses concentric or linear micro-groove structures to redirect LED light and create a desired illumination pattern.

What does a 500mm focal length mean for an LED Fresnel lens?
A 500mm focal length defines the lens's principal focusing geometry and provides an important reference for positioning the LED source and other optical components within the lighting system.

What is the advantage of a rectangular Fresnel lens?
A rectangular format can make better use of available space in elongated LED fixtures, display lighting modules, and other equipment with non-circular optical apertures.

Can a 470×260mm Fresnel lens be customized?
Yes. The manufacturing range supports rectangular lenses up to 470×260mm, while optical parameters can be evaluated according to the requirements of the customer's LED system.




Applications

LED Luminaires
For lighting architectures requiring controlled forward illumination and directional output.

Large-Area Lighting Modules
The 470×260mm format can accommodate optical layouts using elongated or distributed LED sources.

Architectural Lighting
Useful where optical geometry needs to follow a rectangular fixture rather than a circular aperture.

Display & Illumination Equipment
Can be evaluated for systems requiring controlled light-field formation from LED sources.

Specialized Optical Assemblies
Suitable for OEM projects where focal length, dimensions, and Fresnel geometry need to be coordinated with the customer's optical architecture.
