Binocular Design Instructions arm-104.jpg__PID:4ace81e4-c704-45b0-9557-08791eceb5b7

Binocular Design Instructions

1). The LOE structure of the light waveguide lens in the left and right light engine modules is designed symmetrically.
2). The casings of the light engine modules and OELD screens on the left and right are designed symmetrically.
3). The recommended distance between the eyeball and LOE should not be more than 22mm.
4). The recommended design value for the distance between the display centers of the left and right eyes is 63.5mm (corresponding to the human eye's pupil distance).

Positioning Plane

The waveguide plate serves as the positioning benchmark in the assembly process of various parts of the light engine module, and it has the highest accuracy in form and positional dimensions. It can be used as the primary positioning plane for the assembly of the light engine module and the glasses case:1). LOE Front Plane: Positioning in the front and back direction.2). LOE Top Plane: Positioning in the up and down direction.3). LOE Side Plane: Positioning in the left and right direction.

Fixing Method

Design the internal waveguide plate contour of the front shell of the glasses to be consistent with the above positioning plane contour. Correspond the position of the above positioning plane one by one with the position on the surface of the light engine module, and fix the light engine module to the glasses case (to ensure the strength of the front shell of the glasses).
