Unique Light Engines

Creating Outstanding
Images in AR Glasses

By combining the intensity of ultra-bright laser light with the precision of high-quality LCoS display panels, we deliver exceptional image quality.

Highly efficient design

The Quantum Light Chip (right picture) emits highly collimated light, enabling an exceptionally efficient design of the optical path within the light engine. Conversely, LEDs, with their broader emission angles, result in significant optical losses (left picture). Moreover, light emitted from the Quantum Light Chip is polarized, whereas the unpolarized LED light requires polarization, consequently diminishing its brightness even further.

Power Saving through
Local Illumination

The Local Illumination Technology divides the Quantum Light Chip into distinct zones, each powered by its own set of RGB laser diodes. This ensures that only the LCoS surface that is necessary for the image is illuminated, significantly enhancing the overall efficiency of the light engine.

Best Performance

Suitable for outdoor use

Highest brightness

Best image quality

Very small size

The Quantum Light Chip sets new standards for brightness trough multiple sets of RGB single-mode laser diodes. The chip’s homogeneous light distribution provides an optimal illumination source for LCoS based light engines.

A common artifact in laser-based imaging caused by laser coherence is known as speckle. Vitrealab has integrated a despeckler which eliminates coherent artifacts and provides perfect images.

The minuscule size of laser diodes and the dense network of waveguides inside the Quantum Light Chip result in a highly compact light engine of less than 1 cc.

Energy Efficiency

Wide field of view

Color and resolution

The combination of highly collimated laser light and a carefully designed light path within the light engine ensures high luminous efficacy across the entire system.

The wider the FOV, the larger the projection that appears before the eye. Thanks to the high brightness of the light source, even larger images remain clearly visible to the user.

The characteristic wavelengths of RGB laser diodes enable a broader color range than LEDs. The collimated laser illumination of the high-resolution LCoS, delivers crisp images.
