A pattern of pyramid structures machined uniformly in a grid array on a flat surface. Used for retroreflective and light-control materials as well as decorative pattern films.

A pattern of V-shaped grooves machined in crossing directions to form overlapping waves. Applied to security films and decorative materials using optical diffraction effects.

A pattern combining gentle lenticular curves with a mirror finish. It delivers soft light diffusion and high reflectivity simultaneously and is used in display optics.

A pattern combining lenticular curves with prism structures. It provides light-collecting and diffusing functions at the same time and is used for high-performance optical films.

A pattern of uniformly arrayed fine trapezoidal structures. The micro-structures, hard to identify with the naked eye, are applied to anti-counterfeiting security materials.

A pattern of precision-machined cube-corner structures with three mutually orthogonal faces. Because it returns incident light toward its source, it is used for road signs and safety reflective materials.

A pattern of fine needle-like protrusions precision-machined in a uniform grid array on a copper plate. Through polymer replication it is used in medical and bio applications such as transdermal drug-delivery patches and cosmetic needle patches.
