Diffractive optical element Resin light guide plate for AR
Nalux Co., Ltd.
About This Product
By combining AR (Augmented Reality) technology, which displays digital information in the real world, with smart glasses, which are eyeglass-type wearable devices, it is possible to superimpose digital information on visual information in the real world.
For example, in the manufacturing industry, when technicians use smart glasses to maintain or repair equipment, AR technology can be used to visually display procedure manuals and parts locations. It can improve work efficiency and reduce errors. In addition, it is expected to be used for a variety of other purposes in the future, including medical care and entertainment.
Nalux's diffractive light guide plate (Waveguide) for smart glasses is a lightweight and highly safe resin flat plate with a fine shape similar to a diffraction grating on the surface, allowing incident light to propagate through total internal reflection and towards the eyes. Project.
Since the flatness of a flat plate has a great effect on image resolution, it is essential to reduce TTV (Total Thickness Variation) as much as possible. This allows us to create a light guide plate with a low resolution and high resolution.
■Features
- Optical software that utilizes the RCWA (Rigorous Coupled-Wave Analysis) method shortens development lead time.
・Using Nalux's advanced lithography technology, large-area, segmented micro-shapes are precisely manufactured. This reduces uneven brightness.
・High-precision processing of microscopic shapes that generate asymmetric diffraction order light at the light incidence part. Improves light efficiency for brighter and clearer output.
- Highly accurate transfer of fine shapes with an aspect ratio of 1 or more, and injection molding into flat plates with excellent flatness. Achieves high image quality without distortion while keeping costs down.
- The layout of the in-coupler, EPE, and out-coupler can be freely customized. Balances design and functionality.
Single color compatible (full color available upon consultation), ideal for large-diameter spot light sources, currently selling only the light guide plate (we can consult about the protection and external shape of the light guide plate), available for trial use of developed products
■Application usage example
・Translation of foreign languages and real-time display of conversations for people with hearing loss
・Evacuation route guidance and destination navigation during disasters
・Measure and display heart rate, speed, and altitude changes during exercise in real time
■Related patent examples
・JP7309251
・Multiple other patent applications and applications in progress
