Light Guides

Light guides are optical components designed for efficient light transmission. Through advanced material research and precision manufacturing processes, Eata Ray provides high-quality light guides in various specifications. We rigorously control the entire process from raw material selection to finished product inspection, ensuring low transmission loss, high light uniformity, and excellent environmental adaptability. We also offer customized solutions to meet specialized requirements in industrial lighting, medical equipment, laser systems, and consumer electronics.

Applications of Light Guides

Light guides are optical components that efficiently transmit light using the principle of internal total reflection. They direct light emitted from a light source to a target location while maintaining light intensity and directionality. Light guides feature high-efficiency light transmission, flexible shaping, and uniform light distribution, making them widely used in industrial, medical, and electronic applications.

Custom Light Guide

Round Light Guide

Circular light guide rods are highly efficient light transmission components centered around a cylindrical structure. Constructed from high-transparency glass or optical-grade plastic materials, they achieve total internal reflection for light transmission through precision-polished surfaces and optimized refractive index matching. These components offer low loss, high uniformity, and excellent environmental adaptability.

Product List

Features

High-Efficiency Optical Transmission: Utilizes high-purity transparent materials combined with precision polishing techniques to achieve near-lossless total internal reflection transmission.
Uniform Light Distribution: Surface diffusion coating design ensures even light emission from both end faces and sides, eliminating light spots and dark zones to meet high-precision illumination requirements.
Flexible Customization: Supports tailored diameter, numerical aperture, and length specifications. Capable of bending, branching, or integrating multi-channel structures to accommodate complex optical path designs.
Exceptional Environmental Resistance: Quartz material offers high-temperature resistance and corrosion resistance, while plastic material provides lightweight construction and impact resistance, making it suitable for extreme industrial or medical environments.

Multi‑faceted Light Guide

Multi-faceted light guides are optical components that achieve efficient light manipulation through a polyhedral prism structure. Leveraging the total internal reflection and refraction properties of prisms, they precisely distribute light along predetermined paths to multiple output ports or specific directions. These components are suitable for scenarios requiring beam splitting, beam spreading, or complex optical path integration.

Product List

Features

Precise Light Splitting: Through coordinated design of prism angles and material refractive indices, light is distributed to different channels at fixed ratios, meeting the demand for synchronous transmission of multiple optical signals.
High Light Efficiency Uniformity: Anti-reflective coatings on prism surfaces or micro-structural diffusion treatments eliminate optical loss and dispersion during splitting, ensuring uniform light intensity across all outputs. This makes it suitable for high-precision illumination or sensing applications.
Environmental Stability: UV-resistant surface coatings ensure adaptability to industrial environments involving humidity and vibration, guaranteeing long-term reliability.
