Customized Clear Glass Optical CaF2 Window

      Customized Clear Glass Optical CaF2 Window

      Optical Window is one of the basic optical components in optics. It is an optical flat panel that protects electronic components/ sensors/ semiconductors in the optical path. The window does not change the optical magnification and only affects the optical path in the optical path.

      Example with BK7 material：These N-BK7 Meniscus Lens are available uncoated or with one of five antireflection coatings (-A, -AB, -B, -C, or -D), which reduces the amount of light reflected from each surface of the lens (see the Selection Guide table below for coating option). Since approximately 4% of the incident light is reflected at each surface of an uncoated substrate, the application of an AR coating improves transmission, which is important in low-light applications, and prevents the undesirable effects (e.g., ghost images) associated with multiple reflections. Having optics that are AR coated on both surfaces is particularly desirable for applications utilizing multiple optical elements. Please see the Graphs tab for additional coating information.
