Film formation by stacking dozens of layers of multiple dielectric materials! Used in projectors and other applications.
The "Dichroic Filter Coating" is an optical filter that utilizes the interference of light through thin films to transmit or reflect light in specific wavelength regions. In projectors, color separation filters are used, and in digital cameras, infrared cut filters are placed in front of imaging sensors that have sensitivity characteristics in the visible to near-infrared wavelength range, adjusted to match the sensitivity of the human eye. Our company manufactures high-quality DFC with high reproducibility and reliability using Ion Assisted Deposition (IAD) for film formation. 【Main Products】 ■ Projectors ■ Digital Video Cameras ■ Lighting *For more details, please refer to the related links or feel free to contact us.
