AR Optics Startup LetinAR Raises $3.6M in Series A

LetinARLetinAR, a Seoul, South Korea-based startup developing a new optical solution for augmented reality (AR) smart glasses, raised $3.6m in Series A funding.

Backers included Kakao Ventures, Naver Corporation, DSC Investment, Korea Asset Investment Securities, and Platinum Technology Investment.

Founded in October 2016 and led by CEO Jaehyeok Kim, LetinAR develops an optical system for AR smart glasses, which plays the same role as smartphone displays. The optical system consists of LetinAR’s self-developed “Pin Mirror (‘PinMR™’) lens” and a microdisplay made by external partners.
The company, a member of the K-ICT Born2Global Centre, has applied the “Pinhole Effect” to tiny mirrors and embedded them with eyeglass lenses. Respective PinMR™ reflects the light from a microdisplay and guides the light into human pupils. Users may view the virtual image from the microdisplay as well as the image from the real world at ease. Human eyes cannot detect the mirrors because the mirrors are smaller than human pupils. Only the virtual image formed by the light reflected by those mirrors becomes visual.

LetinAR plans to supply PinMR™ Lens as a complete module, which consists of PinMR™ lens and a microdisplay from external partners, next year, enabling smart glasses manufacturers to evaluate the potential of using the lens for their own products.
