Anti-reflective or "AR" coatings are the most common type of optical coating in the world. Applied to elements from eyeglasses and camera lenses, to components used in high-power laser systems, AR coatings are designed to minimize natural back reflections that could otherwise interfere with the preferred operation of an optical system.
Esco Optics offers a range of AR Coatings, including:
The Index of refraction of magnesium fluoride is ideal for the task of providing minimum reflectance with only a single layer of film. When applied at high temperatures, MgF2 becomes a hard, durable coating that meets all standard MIL requirements.
It exhibits broadband characteristics and can be applied on a variety of substrates for use in spectral regions from UV to NIR. MgF2 has the best performance/cost ratio of any anti-reflection coating available today.
