Laser Beam Scanning displays are gaining momentum for use in Augmented Reality Smart Glasses. LBS displays use a compact MEMS-based projector and produce a bright image with rich colors by scanning a laser beams emitted from compact laser diodes for red, green and blue colors. Materion Optics Balzers offers small size and weight RGB laser combiner assemblies with excellent optical characteristics and highly accurate mechanical tolerances for minimal pointing error of the output laser beam.
Chamfer-free glass processing and edge-to-edge coating on our combiner assemblies allows us to manufacture some of the smallest and lightest components available in the market – perfect for the use in stylish and ergonomic smart glasses.
