Holographic Photoresist

With nearly flawless simulation results and an execution plan in hand, we must extend these high standards to the physical lenses themselves; this places extremely rigorous demands on the materials used for their fabrication. Fortunately, we also possess mastery over the entire production process for this specific material—holographic photoresist.

What you actually see？

Lenses coated with this material remain visually stable—unaffected by variations in the underwater environment, sudden changes in lighting, or prolonged use—thereby fundamentally eliminating the issue of a highly inconsistent user experience.

How we made it possible？

To achieve this effect, we employ a proprietary photopolymer formulation developed entirely in-house—comprising organic monomers, initiators, various additives, and curing agents. The resulting holographic photoresist offers distinct advantages: high refractive index modulation, minimal material shrinkage, and high transmittance. It is through the subsequent application of our holographic lithography process that the resulting optical waveguide lenses are able to deliver such stunning visual effects.

Why does it matter?

1. Born for Design Ideals——From the Pursuit of Perfection to a Precision Medium

To ensure that the visual effects envisioned in our blueprints and models translate as faithfully as possible into reality, we have relentlessly refined our lens materials. These materials meet rigorous standards, boasting high light transmittance, an ultra-lightweight and slim profile, and a compact form factor. Within the lens, we utilize holographic photoresist to "grow" a precise optical pathway. This specialized material—highly sensitive to light and acting like a "nanoscale photographic film"—enables us to use lasers to precisely "write" the ideal light paths derived from our optical simulation models, permanently embedding them into the lens structure.

2. Ensuring Precise and Controllable Display——From Functional Materials to Stable Imaging

We apply this material onto a resin substrate, utilizing it as a "canvas" to render images that are crystal-clear, distinct, and flawless. Once inscribed by the laser, the photoresist transforms into a micro-nanostructure endowed with specific optical functions. It serves simultaneously as a "guide," directing the path of light, and as a "switch," precisely redirecting the image directly into the wearer's line of sight—thereby ensuring that the image remains perfectly stable within the field of view, regardless of head movement.

3. Delivering a Consistent Experience—— From Simulation Optimization to Environmental Adaptability

Our goal is to ensure that from the very moment a user puts on the product, they enjoy a flawless athletic experience—regardless of the external environment. Unlike the traditional approach of "building the product first and debugging later," we begin by optimizing every parameter within our optical simulation models. We then use holographic photoresist to "replicate" this rigorously refined simulation data directly into the physical lens in a single, seamless step. This process locks in the ideal performance right from the source, ensuring the device remains impervious to the various environmental challenges encountered during active use.

Why we are different?

Most systems follow a conventional approach——lenses are fabricated first, installed, and then fine-tuned. However, this often reveals issues such as ghosting or image drift; furthermore, being constrained by physical prototypes, it becomes extremely difficult to implement fundamental optimizations.

Our approach is different——we begin by optimizing all critical parameters—including light paths, image stability, and field of view—within an optical simulation model until they approach an ideal state. We then utilize holographic photoresists to "replicate" this rigorously refined simulation data, in a single step, into physical lenses that function seamlessly in the real world.

How are we able to execute this strategy? At our core lies a "technology-driven" engineering culture. Our senior executives—including our CEO and CTO—hold Ph.D.s in science and engineering disciplines. They lead three core teams—specializing in optics, materials science, and micro-nanofabrication—to develop our proprietary holographic photoresists and simulation software, all built from the ground up based on first principles.

What is the actual use case?

Whether gliding through a brightly lit indoor standard pool, navigating the ever-changing conditions of open-water environments, or even traversing through dense, canopy-shaded forests, Holoresin™ delivers top-tier visual performance throughout your entire journey—maintaining consistent brightness and clarity, entirely unaffected by any external environmental factors.

Holosport’s Holoswim 2s, Holoswim 2 Go, and Holoswim 2 Pro models all feature this technology.

What is Next?

We now possess the necessary hardware and software to produce a perfect pair of lenses; however, to achieve mass production—while ensuring that every single pair meets such exacting standards—we must also master one specific technology: the holographic lithography system.
