Virtual Reality, Light Management and Black Coatings

Virtual reality (VR) devices have revolutionized the way we experience digital content by immersing users in simulated environments. These devices come in various forms, from standalone headsets to more complex setups requiring external sensors and powerful computers. However, regardless of the type of VR device, they all share a common need for effective light manipulation to create immersive experiences.

Light management is crucial in VR to ensure that users perceive realistic visuals and prevent distractions that can break the immersion. One important aspect of light management is the suppression of stray light – unwanted light entering the user’s field of view from outside sources. Stray light can diminish the quality of the VR experience by reducing contrast and clarity, making it harder for users to focus on the virtual environment. Another challenge in VR design is the need to block or prevent scattered light from interfering with the display. Scattered light can cause visual artifacts and  distortions  leading to a less immersive experience.

Light absorbing low reflective coatings are a crucial element in meeting these challenges. They serve multiple purposes. A high-quality black coating absorbs stray and scattered light, preventing it from reaching the user’s eyes and thus improving contrast and image quality. Additionally, black coatings help minimize reflections within the device, further enhancing the visual experience

To be successful it is essential that the black coatings do not release outgassing which could fog lenses and that they do not outgas volatile compounds from the coating material which would deposit onto the lenses over time. Furthermore, black coatings must be durable to Ultraviolet to the extent necessary in accordance with their location in the system.

It is in this context that Acktar Black light absorbing coatings contribute. Acktar coatings deliver the best optical performance in the industry together with an array of features and advantages which make them eminently suitable for meeting the challenges described above.

Acktar black coatings can be deposited virtually on any material: polymers, glass, ceramics and all metals

  • Hemispherical Reflectance under 1.2%
  • Thickness – only 2-3  microns

In conclusion, light management is a critical aspect of VR device design, and black coatings play a vital role in enhancing the immersive experience for users. By effectively suppressing stray and scattered light while minimizing side effects, black coatings contribute to the overall quality and enjoyment of virtual reality content.
