What material is used to form the mica sheet?

　　As is well known, to extend the lifespan of electronic devices, their surfaces are typically coated with a layer resembling a “protective film.” While it may appear to be plastic, it is actually Mylar. Today, this material has found applications across numerous fields, rapidly gaining prominence and successfully capturing a significant share of the market. What advantages does it possess that have enabled it to achieve such remarkable success in such a short time?

　　Mylar film is primarily composed of dimethyl terephthalate and ethylene glycol, which, under the action of appropriate catalysts, undergo a chemical reaction to form a new material. Mylar film boasts numerous advantages, enabling it to thrive across a wide range of industries. First, it offers an exceptionally diverse palette of colors—unlike conventional protective films that typically come in a single shade, Mylar film is available in a dazzling array of hues. Second, its variety is staggering, with each type possessing unique benefits; this diversity allows businesses to select the most suitable option based on their specific needs. Finally, Mylar film exhibits outstanding properties: thanks to specialized manufacturing processes—including heating, ester exchange, vacuum compression, and biaxial stretching—it achieves remarkably stable chemical characteristics, such as excellent wear resistance, thermal stability, water resistance, and corrosion resistance. Perhaps its most significant advantage is its superior electrical insulation.

Ion Coating Dramatically Reduces Baffle-Ring Reflectance

Yamagata Optical's ion-coating process reduces baffle-ring reflectance by a factor of 8.6. In addition to multiple solutions for suppressing stray light at the aperture edge, we can apply an ultra-low-reflectance ion coating to both sides of the film used to manufacture baffle rings. After treatment, reflectance can fall below 0.3%, substantially improving camera-module optical performance.

Yamagata Optics lens hood ion plating technology

After ion-plating treatment, Yamagata Optics has achieved an 8.6-fold reduction in the reflectance of its aperture. Currently, in addition to multiple anti-glare and stray-light suppression solutions for the inner bore of the aperture, Yamagata Optics can also apply ultra-low-reflection ion-plating to both sides of the raw-material light-shielding film. Following this anti-reflection treatment, the reflectance can be reduced to below 0.3%, significantly enhancing the optical performance of the camera.

The Ultra-Black Revolution in Optics From 5% to 0.1% Reflectance: How Yamagata Optical Is Advancing Photonics

In optical imaging, light can be both essential and disruptive. An unwanted ray may reflect off a lens-barrel wall, scatter from a spacer ring or diffract at a baffle edge. The result can be ghosting, halos, light streaks, ripple-like artifacts or veiling glare that washes out the image. Together, these forms of stray light undermine image clarity, contrast and signal-to-noise ratio.
