SCHOTT® LightView packages

Hermetic packaging components for augmented reality (AR) aim to transform the experience from bulky and unwieldy to sleek and effective. Specially developed for RGB lasers and MEMS mirror packages, SCHOTT® LightView miniaturizes and enhances opto-electronic performance for AR light engine systems.

The technical challenges for augmented reality

Augmented reality (AR) is widely accepted to be one of the most exciting technologies in development today, opening up a range of opportunities for businesses around the world. But for AR to reach its full potential, there are a number of technical challenges to overcome.

One of the main challenges is achieving a broad colour gamut and high resolution for image projection, which will drive business and consumer interest. Since AR technology will be used both inside and outside, high brightness will be required to provide effective contrast alongside the efficient coupling of light to the waveguide. Both factors have direct impacts on battery consumption.

In addition, sleek form factor is vital if consumers are to embrace and invest in the technology. However, existing packaging solutions are bulky, resulting in undesirable large form factors for end devices in many cases.

Exceptional opto-electronic performance

SCHOTT optical glasses, lenses, and windows are developed and processed to an extremely high quality standard for light engine systems, with customized glass window sizes and angled windows both possible. Special treatments, such as AR coatings, can be applied to achieve even higher transmission, while the flat base with flushed pins can be soldered in a typical SMD style.

The benefit of experience for augmented reality

SCHOTT has utilized its long-standing experience in glass-to-metal sealing to develop innovative packaging solutions for RGB laser chips and MEMS mirrors in augmented reality applications.

SCHOTT® RGB LightView Package

The SCHOTT® RGB LightView Package enables the adoption of laser-based light engine technologies for augmented reality and HUD applications. Hermetic encapsulation protects the sensitive RGB laser chips to enable high brightness and image resolution. Other advantages include:

  • Three-times form factor reduction compared to individual TO cans.
  • Hermetic encapsulation that increases the reliability of RGB laser chips.
  • Cost-efficient, localized joining of metal base and cap.
  • Excellent optical properties through the use of SCHOTT’s in-house optical glass.
