Light Absorbing/Anti Reflective Platings
Mitsuya offers black nickel plating as a solution to prevent the reflection of light by darkening the surface. This type of plating serves as a selective absorption material, efficiently absorbing sunlight and converting it into heat. It also helps in reducing heat loss through radiation from the heated absorbing material itself.
The absorption properties vary depending on the wavelength of light: in the solar light wavelength range (0.3 to 2.5 μm), the absorption rate is higher, while in the infrared wavelength range (3.0 to 20 μm), the emissivity is smaller, resulting in better absorption.
This makes Mitsuya's copper-blackening deposit ideal for various optical products like ultraviolet, visible, and infrared absorbing films, as well as for applications in stray light removal, projectors, microscopes, spectroscopic apparatuses, laser processing machines, infrared detecting elements, and more.
