DEVELOPMENT HISTORY/AIM OF A REVOLUTINAORY POLARIZER

DEVELOPMENT HISTORY/AIM OF A REVOLUTINAORY POLARIZER

Under the comprehensive supervision of Mr. Tatsuno Kiyoshi, a groundbreaking limited edition filter was born after an 18-month development period, aiming to be unparalleled in every aspect of Polarizer in its history.

PLASMA SPUTTERING COATING

PLASMA SPUTTERING COATING

Plasma sputtering coating, a fascinating technique in materials science and engineering, involves the deposition of thin films of material onto a substrate through sputtering. This process is achieved by ejecting material from a "target" material to the "substrate" using a plasma.

NO SCRATCH AGAINST STEEL WOOL

In plasma sputtering, the kinetic energy of the particles of the coating material is higher than in conventional vacuum evaporation methods, resulting in a highly adhesive and strong film.
Moreover, since it is smooth and has extremely little resistance due to to the flattness, it is less likely to get scratched.

IMPORTANCE OF OPTICAL FLATNESS

In optics, the flatness of glass is crucial because it affects how light is transmitted and reflected, which in turn influences the quality of the images produced. When using a camera filter, the presence of Newton's rings in the flatness testing can significantly degrade the actual image quality. Whether or not flatness can be maintained without the appearance of Newton's rings greatly affects the quality of the product.
