Ames Osram and Longjing Optoelectronics, Vegas ™ RGB laser module helps LBS AR module
2023-01-31

December 22, 2022 - The world's leading optical solution provider Ames Osram (Swiss Stock Exchange stock code: AMS) announced that it would work with the leading AR near-eye display optical module supplier Longjing Optoelectronics to promote the development of portable intelligent glasses. The latest LBS diffraction waveguide AR module and prototype glasses released by Longjing Optoelectronics adopt the new Vegalas of Ames Osram ™ RGB laser module.

For a long time, the market of AR and MR smart glasses is mainly in industrial or professional applications. This is due to the difficulty of lightweight, large size and heavy weight of components such as optical engine or battery for projection, and the need for solid frame as support. Via Vegas ™ Module prototype, the size of the optical engine of smart glasses can be greatly reduced, which is suitable for standard consumer fashion frames.

The laser beam scanning (LBS) diffraction waveguide and prototype glasses AR module recently launched by Longjing Optoelectronics, which uses Ames Osram Vegalas ™ RGB module realizes the close-eye display solution with compact size, light weight and high brightness. At the same time, LBS technology can effectively reduce the power consumption of image content in intelligent glasses applications.

Vegalas ™ Laser emission module can reduce the size of intelligent glasses projection optical engine by half

Ames Osram Vegas ™ The design of the module combines red (640nm), green (520nm) and blue (450nm) wavelength lasers, and adopts surface mount packaging technology, which is strictly sealed to prevent chip from being damaged or degraded. The size and area of the module is 7.0mm × 4.6 mm, 1.2 mm thick

Longjing Optoelectronic LCE2109 LBS optical engine solution with this module is only 11.2mm in size × 11mm, 5mm thick. After the light source is collimated, the non-projection light path can directly emit light. Compared with the traditional light engine that requires multiple lenses and prism projection, it not only reduces the volume, but also reduces the cost. The solution supports a maximum of 56 ° angle of view (FOV). Because the solution uses scanning imaging, it can achieve higher contrast, and the imaging beam has good collimation and no convergence error. It has more advantages in experience effect and long-term wear. The output brightness of this scheme can reach 10lm, and the power consumption is lower than that of the ordinary scheme, which is lower than 350mW.

"Through the diffraction waveguide AR module based on LBS, Longjing Optoelectronics has helped customers realize more portable smart glasses and opened the door of consumer-grade smart glasses. We are very happy that Ames Osram Vegalas ™ The excellent performance of the laser module has laid a good foundation for reducing the size of the optical engine. " Ma Guobin, chairman of Longjing Optoelectronics, said.

Both Ames Osram and Longjing Optoelectronics are members of the Lasar Alliance, Laser Scanning for Augmented Reality, lasaralliance. org. The two sides have established a partnership to share information about laser scanning technology, and have conducted in-depth cooperation in the development of components, equipment and technology.

LaSAR is a project of IEEE Industry Standards and Technology Organization (IEEE-ISTO). The organization is committed to providing its customers with legal and financial infrastructure, and providing corresponding support for the development of standards and the market application of emerging technologies.
