Additionally, to thoroughly eliminate ghosting and lens flares, reflectivity was kept to half of the previous value at a wavelength of 450 to 650 nm, thanks to the lens surface treated with the Olympus-original ZERO (ZUIKO Extra-low Reflection Optical) coating.

They are then mixed together to create a grey powder that floats in alcohol over the surface of the lens.

The output is then relayed into a 1.4 mm thick plastic waveguide lens with input and output hologram structures on the surface which squeezes the light down the waveguide and then two dimensionally expands the image back into the user's eye, creating an image that is then mixed into the real world.
