It removes and absorbs more than 99% of stray light and scattered light across ultraviolet, visible, and infrared wavelengths (with wavelength dependence).
Actor Corporation has developed a vacuum deposition technology that achieves over 99% light absorption across ultraviolet, visible, and infrared wavelengths. This technology enables the deposition of light-absorbing films on virtually any substrate material, effectively eliminating stray light (scattered light) in various optical products such as projectors, microscopes, spectrometers, laser processing machines, and infrared detection devices. Additionally, by controlling the surface structure at the nanoscale, we have successfully developed an ideal solar thermal selective absorber material that combines optimized spectral characteristics for solar heat absorption with heat resistance. It also excels in absorbing radiant heat and is utilized as a groundbreaking radiant heat absorption film in various thermal environments. This environmentally friendly technology is used in a wide range of industries, including optics, electronics, space, and energy.
