Goeroptics Unveils New AR Waveguides and 3D Printing Light Sources

Goertek Optics Technology Co. (“Goeroptics”), a subsidiary of Goertek, has introduced new optical modules at SPIE AR | VR | MR 2025 and TCT Japan. These include the full-color AR waveguide module Star G-E1 and a high-precision DLP-based light engine for 3D printing. These developments highlight the company’s ongoing expansion in the field of optical technologies.

The Star G-E1 module is based on high-refractive-index materials and etching technologies for surface structuring. It features high brightness, low stray light, and uniform color reproduction, ensuring clear displays even in bright environments. Compared to traditional nanoimprint techniques, the optimized grating structure enables a broader range of refractive indices and increased UV resistance. The module achieves a peak brightness of 5,000 nits and brightness uniformity exceeding 45%, with a color deviation of less than 0.02. This significantly enhances color performance, resulting in sharp and accurate images. With a thickness of just 0.7 millimeters and a particularly compact micro-LED light module with a volume of less than 0.5 cubic centimeters, the Star G-E1 is ideal for lightweight and compact AR glasses.

In addition to AR applications, Goeroptics introduced a new DLP light engine for 3D printing. Supporting resolutions of up to 4K, it improves print accuracy. A high light output of 3W reduces the curing time of printing materials, speeding up the process. The contrast ratio of over 1000:1 minimizes residue and enhances the detail sharpness of printed structures. A uniform light distribution of 90% ensures sharp edges and precise surfaces. Distortion remains below 0.1%, ensuring accurate geometries and dimensional stability. The use of glass lenses and metal components guarantees high stability and durability, even during extended operation.

Goeroptics also presented new 3D scanning light modules that project structured light patterns to enable precise surface measurements. Another highlight was the laser module, which utilizes line laser technology to capture detailed 3D contours of objects. These technologies are applied in fields such as electronics inspection, lithium battery analysis, and PCB manufacturing. Since 2017, Goeroptics has been developing DLP projection light sources and continuously improving micro- and nanocomponents for optical systems. In the future, the company aims to expand its research and manufacturing capabilities to provide high-performance and cost-effective solutions for industrial and scientific applications.
