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.
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.
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.
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.
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.
