Amazing Reality

All-Day, All-in-One, All-Around
AR Optical System

LetinAR has developed PinTILT, the hybrid structure consisting
of advantages of both waveguide and birdbath AR optics.


CTO of LetinAR made a groundbreaking discovery while observing a partial solar eclipse on July 22, 2009.

About Us

LetinAR was founded by two high-school mates to share this ingenious AR technology with the world. Today, like-minded LetinARians are working together to actualize this vision.


LetinAR made an innovation of AR Optics that developed from scientific discoveries.

We currently provide optical modules for Augmented Reality and evaluation kits, including smart glasses to utilize these modules.

  • Letinus™ Lens Module

    The Letinus™ Lens module is a compact lens module. It features a lightweight design and is ideal for the development of smart glasses that can be worn for extended periods of time, thanks to its 22-degree field of view (FOV) and low power consumption.

  • T-Glasses (Letinus™ EV-Kit)

    T-Glasses is an EV-Kit in the form of glasses that utilizes the Letinus™ lens module produced through standardized processes. It has been in high demand and sold out quickly to over 14 global companies in the past year. With limited stock remaining, we urge you to act swiftly to secure your order!

  • FrontiAR™ Lens Module

    The FrontiAR™ module is the successor to the previous version, the Letinus™ module. It is ideal for developing wide-angle smart glasses with a wide field of view of 45 degrees, low power consumption and a lightweight design.

  • KeplAR (FrontiAR™ EV-Kit)

    KeplAR is an EV-Kit in the form of glasses that incorporates the FrontiAR™ module. It offers a wide field of view of 45 degrees. With low power consumption and a lightweight design, it is suitable for developing applications in everyday and industrial environments. It is scheduled for release by the end of 2023.

  • FrontiAR™ Pro Lens Module

    The FrontiAR™ Pro Lens module is a variation of the FrontiAR™ Pro Lens module that does not use a pin mirror. It enhances optical uniformity and provides a cleaner field of view. It is scheduled for release in late 2024.
