Optical engines for AR benefit from reflective waveguides


Two optical engines developed by Lumus make use of Lumus’ 2D reflective waveguide technology to provide AR (AR) glasses. After the success of its Maximus 2D expanding waveguide displays that was introduced in the last 18 months The company is now expanding its Maximus range to meet the specific demands from customers for the mass manufacturing of AR glasses that are priced to appeal to the market of consumers.

The glasses are designed to appear like normal eyeglasses, and are designed to be worn all day long, the Maximum 1080P optical engine has the 40deg field of vision and a brightness of more than 4000 nits, and a resolution that is 1080 pixels. It is a 12×12-mm box that has the aspect ratio 16:9. Another optical motor, called the Maximus 1440 2P has a 50deg wide field of vision, a brightness that is greater than 3000 nits and a resolution of 2. pixels. The Maximus 1440 also comes with an eye-box that is 12×12 millimeters and the aspect ratio of this device is 1:4 to allow for greater immersion.

Both devices share the advantages that come with their 2D reflective waveguide technology brightness that is able to perform even in full sunlight, a smooth image with unbeatable battery efficiency and uniform color, resulting in pure white. Multi-patented, reflective waveguide design makes use of the simple concept use of mirrors that partially reflect to focus light from a micro-projector and virtually eliminate loss of light to the front.
