These are the first and only mass-produced coated lenses for Project North Star, Leap Motion's Open Source AR headset project. We've used them on our own builds, and as you can see, they work beautifully.
The biggest roadblock for those looking to build their own North Star headsets has been fabrication of the reflective lenses. People have been spending around $200 to have uncoated reflectors milled with a diamond tip from a big block of acrylic. They’ve been quoted prices up to $400 to have them coated with the half-reflective silver mirroring and the anti-reflective coating that prevents an unwanted secondary reflection from the lens’ outer surface.
Well, consider this roadblock removed. Good luck with your North Star build!
Note: The mounting tabs on the lenses have been slightly modified to improve the injection molding results. These optics brackets have been modified to accommodate the new tabs. The tabs can also be trimmed, and older brackets can be modified with a rotary tool.
Please note that the North Star design is not glasses-friendly. If you need corrective lenses, you’re going to need contacts to use North Star. We know that this sucks, but it is what it is.
