SAN FRANCISCO, CA, Feb 7, 2025 – Goertek Optics Technology Co. (Goeroptics), a subsidiary of Goertek, has unveiled its latest full-color augmented reality (AR) waveguide module, Star G-E1, and its proprietary DLP (Digital Light Processing) 3D printing light engine at the SPIE (International Society for Optics and Photonics) AR | VR | MR 2025 and TCT Japan, highlighting the company’s advancements and expansions in the optics sector.
The Star G-E1 module, featuring high-refractive-index materials and etching surface relief grating technology, delivers incomparable display performance. It boasts high uniformity, brightness, and low stray light, ensuring crystal-clear visuals even in bright environments. The innovation overcomes the limitations of traditional nanoimprint techniques in high-refractive-index material applications, offering a wider range of refractive index options and enhanced UV resistance. By optimizing the grating material and structure, the Star G-E1 achieves a peak brightness of 5,000 nits, with brightness uniformity exceeding 45% and color difference less than 0.02. The improvements represent a 50% and 100% enhancement over similar technical solutions. This reduces image color deviation and elevates color performance, resulting in vibrant, impurity-free images. Furthermore, the Star G-E1 features a sleek, single-layer optical waveguide that is 0.7 millimeters thick. It incorporates a micro-LED display solution, with the light engine volume of under 0.5 cubic centimeters. The compact design delivers optical display performance, paving the way for lightweight AR glasses that provide a delicate, realistic, and natural viewing experience.
The 3D printing industry is growing, and the demand for precise printing is rising. As a result, optical modules in 3D printing machines must meet stricter performance standards. Accurate control of light fields is essential for 3D printing light engines. It helps minimize errors and enhances the quality of the printed products. At TCT Japan, Goeroptics introduced DLP-based 3D printing light engine that. Supporting high resolutions of 4K and 1080P, the module significantly improves printing accuracy. The 3W output power shortens the curing time for each layer of material, accelerating printing speed. The contrast ratio exceeds 1000:1, minimizing print residue. In addition, the light engine boasts 90% uniformity, ensuring that printed product details are sharp, and features are intact. Distortion control is maintained within 0.1%, ensuring that printed products maintain their correct shape and size. The light engine includes an all-glass lens and an all-metal structure. It also has robust thermal management that provides stability and durability during long use, extending the device’s lifespan.
In addition to its 3D printing offerings, Goeroptics showcased its 3D scanning light engines and laser modules for precise 3D profiler measurements. The 3D scanning light engine leverages DLP technology to display various high-resolution structured light patterns, capturing intricate surface details and enhancing 3D model accuracy for a wide range of applications. The laser module, utilizing line laser technology, scans object surfaces to measure their 3D contours. With a Gaussian degree of over 90%, uniform scanning lines, it is suited for inspection tasks in the 3C electronics, lithium battery, and PCB segments. Since 2017, Goeroptics has been developing DLP projection light engines, providing end-to-end solutions from optical design to assembly. The company continues to expand its research and manufacturing capabilities in micro-nano optical components and laser modules.
