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

  • B30 Lens Module

    The B30 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 (B30 EV-Kit)

    T-Glasses is an EV-Kit in the form of glasses that utilizes the B30 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!

  • B40 Lens Module

    The B40 module is the successor to the previous version, the B30 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 (B40 EV-Kit)

    KeplAR is an EV-Kit in the form of glasses that incorporates the B40 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.

  • B41 Lens Module

    The B41 module is a variation of the B40 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.
