VIC Ultra-Low-Reflectance Black Coating

01 Feb,2026

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

Invitation to the 2026 Japan Optoelectronics Exhibition from Yamagata Optics

15 Apr,2026

〇 A mature, stable production system and a precise stray-light elimination solution 〇 Addressing customer pain points—delivering products that deliver real value

The Yokohama Optoelectronics Exhibition in Japan concluded successfully, yielding abundant results.

01 May,2026

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

07 May,2026

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

13 May,2026

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

21 May,2026

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

03 Jun,2026

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

02 Jul,2026

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.

A Breakthrough in Ultra-Low-Reflectance Plastics PCA™ Materials and Ion Coating, Engineered Together

02 Sep,2026

Following rigorous validation, we have developed an engineering-plastic solution that combines ultra-low reflectance with exceptional resistance to demanding environmental conditions.

Ultra-Low Reflectance on ADC12 Die-Cast Aluminum with Ion Coating

09 Sep,2026

Ion coating has demonstrated ultra-low reflectance on ADC12 die-cast aluminum in practical applications. Yamagata Optical has now extended this technology to LiDAR components and a wide range of aluminum castings with internal optical paths that require low reflectance. Reflectance as low as 0.5% matches the performance of machined aluminum components, and the process is now in stable volume production.
