Black oxide, also known as blackening, is a precision conversion coating process used on ferrous materials that provides increased corrosion resistance. When used in optical applications, it also improves operational characteristics that increase the effectiveness of the optical systems.
E-Fab specializes in producing black oxide-coated parts for optics, combining photochemical etching precision with advanced black oxide finishing. These parts enhance optical performance by reducing glare, controlling reflection, and providing a sleek, durable finish. E-Fab’s black oxide parts are engineered to meet the high standards of industries like aerospace, defense, and precision instrumentation.
The ability to blacken optical surfaces with superior precision sets E-Fab apart from the competition. Optical blackening keeps light not intended to pass through an optical system from reaching the image plane, and the process involves surface preparation for roughening and surface treatment for darkening. This manufacturing process offers the following enhancements that ultimately improve the functionality of the optics:
Minimize unwanted reflections in optical systems for improved performance and accuracy.
Provide a uniform, matte black finish that is both functional and visually appealing.
Add an additional layer of protection to extend the lifespan of components.
Unlike other coatings, black oxide maintains the original dimensions of the part, ensuring precise functionality.
Not all materials are compatible with the blackening process. Fortunately, some of the most popular alloys are, which make black oxide parts easily integrated into systems that add an additional layer of durability and precision. Furthermore, E-Fab has decades of experience handling these materials to ensure that your black oxide application is seamlessly integrated into your project to increase the efficiency and longevity of the product.
