Thin Film Optical Coating equipment

Optical coatings are thin layers of dielectric or metallic materials that are deposited onto optical components, such as lenses, mirrors, and filters, to control the transmission, reflection, or absorption of light within a specific range of wavelengths from ultraviolet (UV) to infrared (IR). These coatings are designed to manipulate the behavior of light by reducing glare, enhancing contrast, or improving overall optical performance. Optical coatings are typically composed of multiple thin layers of dielectric materials with varying refractive indices, which are carefully selected and stacked to achieve the desired optical properties. The thickness of these layers is typically in the range of tens to hundreds of nanometers. Therefore, the accuracy of the deposition technologies used to apply these coatings is crucial to achieve reproducible results over the entire surface of the optical component.
