Customization of Mira tablets


  During the production of Mylar sheets, our company can customize their thickness to meet diverse customer requirements. Typically, most Mylar sheets are manufactured in rolls, which makes them more convenient for end‑users. Moreover, Mylar sheets possess distinct characteristics, allowing customers to select products that best suit their needs. However, few customers realize that, when ordering custom‑made Mylar sheets, they can also specify the desired thickness. In addition to shaping, we offer the option to tailor the sheet’s thickness as well.

  However, it’s important to note that due to the unique nature of its raw materials, mica tape production is subject to certain thickness‑related constraints. We cannot simply increase its thickness indefinitely; typically, the thinnest mica tape is around 0.025 mm, while the thickest can reach up to 1.5 mm. If you require mica tape that is even thinner or thicker than these standard ranges, custom fabrication becomes quite challenging, as many manufacturing processes would be unable to meet such specifications. Therefore, when ordering custom mica tape, it’s best to stay within a reasonable thickness range that suits your specific needs.

Yamagata Optics manufactures shutter blades, apertures, bases, lens barrels, caps, spacers, and camera housings, which can perfectly address image quality issues caused by various types of stray light.


Ultra-Low-Reflectance Coatings for Metal Components Over 99.9% Light Absorption

Inside a lens assembly, reflections from metal spacer rings, lens holder, barrel,spacer , baffle rings and the inner walls of the lens barrel can generate stray light. The resulting artifacts include light streaks, halos, ripple-like patterns and ghost images, all of which degrade image quality, as illustrated.


Serrated-Aperture Diaphragms for Stray-Light Suppression

Yamagata Optical's patented serrated aperture-edge design offers clear advantages over conventional wavy-edge designs. This innovative geometry provides highly effective stray-light suppression. It reflects our long-standing commitment to advancing precision optical components through research and engineering innovation.


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.
