T&I has been focusing on the supply of self-developed products and has been
growing steadily in photonics convergence technology since its inception.

Since the early days of its foundation, the company has been developing and supplying various photonics convergence systems from
Windows Tint Meter required by the National Police Agency, auto repair shops, and photonics-related laboratories to the
LED Plant Growth Control System that provides optimum conditions for plant growth.

All of us here at T&I promise to strive for and initiate research and development in the rapidly
changing age of limitless technical competition and to develop and become a reliable company that gains
customers' confidence with technologies that enrich our lives, contribute to social security, and are useful for global markets.

Thank you.
