Composite Prism

A composite pattern combining prisms in two or more directions. It can realize multiple optical properties at once and is used to produce high-performance optical components.

Lenticular

A lens-shaped pattern with gentle curved surfaces; pitches of 100㎛ or more are machined with high precision. Applied to 3D displays and light-diffusion films.

Standard Prism

A basic prism pattern of uniformly repeating V-shaped grooves. Ultra-precision pitches down to 20㎛ can be achieved, and it is used for optical films and display components.

Inclined Prism

An asymmetric prism pattern machined with the tool tilted using the B-axis (tool index). It enables machining of inclined structures that are difficult to achieve with conventional turning.

Pyramid Prism

Grid-type pyramid structures are machined through X·Z·C multi-axis simultaneous control. Used for retroreflective films and high-performance optical materials.

Wave Pattern (FTS)

Wavy freeform patterns are produced by high-speed oscillating machining with an FTS (Fast Tool Servo). It enables non-linear complex shapes that are impossible with conventional turning.

Retroreflection

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.

Security Pattern

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.

Lenticular + Prism

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.

Lenticular + Mirror Finish

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.

Cross Wave

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.

Pyramid

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.

Fly Eye (Lens Array)

A structure of micro lenses machined in a uniform grid array on a flat surface. Its uniform light-distribution characteristics make it suitable for display backlights and projector optics.
