Eyebox on the xReal 2 Ultra

Comparing the eyebox of XReal devices

augmented reality Jul 10, 2024

With the release of the Xreal Air 2 Ultra, one common question is about the size of the eyebox in relation to the Air 2 Pro. Lets take a look.

First the TLDR numbers:

(mm) nReal Air xReal Air 2 Pro xReal Air 2 Ultra
Width 37.4 34.4 37.4
Height 22.0 19.0 22.0
Bridge 31.5 31.5 31.5
Depth 15.5 13.0 16.0
Thickness 20.9 19.0 20.9

The short answer is that is looks like xReal knows they screwed the pooch with the Air 2 and Air 2 Pro and have returned to a much larger eyebox.

The only dimension that remains the same is the bridge distance. The Ultra optical assembly dimensions are nearly identical to the original nReal Air.

xReal specifically calls out the change in panel size here:

Air 2 Ultra Air 2 Pro Air 2 Air
0.70 Sony Micro-OLED ?? 0.55 Sony Micro-OLED 0.55 Sony Micro-OLED 0.68 Sony Micro-OLED

And given that the latest 1080p Micro-OLED panel from Sony is a new 0.70 size panel, it would make sense that this is what is in the Ultra, meaning a nearly identical eyebox to go along with it.

Terminology and photos

Width is distance left to right of the widest point of the clear inner diagonal panel of the optical assembly.

Height is the distance top to bottom of the tallest point of the clear inner diagonal panel of the optical assembly.

Bridge is the distance from the most inner point of the left clear panel to the right

Depth is the vertical distance from the surface of the casing to the top of the tallest point of the clear inner diagonal panel of the optical assembly.

Thickness is the thickest point of the top down perspective of the optical assembly including the casing.
