VIC vacuum ion coating can reduce the reflectance of lens barrels and metal spacer rings to below 0.1%. When combined with Yamagata Optical's PET film baffle rings, which feature a matte black finish on both sides and patented chemical etching of the aperture edges, these components significantly suppress stray light and improve image clarity.

Backed by 20 years of experience in optoelectronics, Yamagata Optical's latest ultra-low-reflectance coating technology for metal components delivers performance well ahead of comparable products. Applications span a wide range of industries.

1. Consumer Electronics

Typical components:
Lens barrels, lens mounts, spacer rings, baffle rings, shims, zoom actuators and mechanical shutters.

Benefits:
Substantially less stray light, a higher optical signal-to-noise ratio, reduced halos and light streaks, and improved image quality.

2. Machine Vision and Inspection

Application requirements:
Accurate image capture and data acquisition, with stray-light control for spacer rings, baffle rings, shims, zoom actuators and mechanical shutters.

Benefits:
Reduced stray-light interference, clearer images and greater inspection accuracy.

3. Precision Optical Instruments

Typical applications:
LiDAR, spectrometers, fluorometers, high-resolution microscopes and intracavity laser optics.

Benefits:
Higher-quality images, less reliance on computational correction and simpler optomechanical designs.

4. Biomedical Imaging

Typical applications:
Endoscopes, ophthalmic microscopy, brain imaging, CT detector windows, microvascular imaging and other medical optical imaging systems.

Benefits:
Clearer visualization of lesions to support accurate diagnosis.

5. Renewable Energy

Typical applications:
Machine vision and solar-panel surface treatments.

Benefits:
Antireflection layers for solar panels and concentrator photovoltaics (CPV) help increase power output. The surface-treatment solutions described here offer greater weather resistance than conventional sol-gel coatings, with a service life exceeding 25 years.
