Optical combiner

Lumus Vision combiner and attached electronics

A combiner is an optical component that merges two optical paths. For example, a small piece of glass in front of an eye that reflects light from a display source.

A reflector like that used in the Project North Star is a type of combiner.

Optical-see through waveguides are combiners. They combine optically the outside world with the electronically rendered light.

Combiners can use HOEs to reflect light in a way where the angle of incidence does not equal the angle of reflection.

Types

• Reflector (Like in Project North Star and Meta 2)
• Diffractive waveguide (Like in the Magic Leap 1)
• Reflective waveguide (Like from Lumus)
• Geometric waveguide (Lumus)
• Holographic optical element
