530-6253 25.4 mm Dia. IR grade CaF2 Window; t=3 mm Uncoated

The 530-6253 is a high-quality optical window, specifically designed for infrared (IR) applications. Manufactured by EKSMA Optics, this window boasts a diameter of 25.4 mm and a thickness of 3 mm, making it a robust and reliable component for various optical systems.

The window is made from Calcium Fluoride (CaF2), a material with a wide transmission range, spanning from the ultraviolet (UV) to the far infrared (FIR) region. This makes it an ideal choice for applications that require excellent transparency across a broad spectrum. The specific grade of CaF2 used in this window is IR grade, ensuring optimal performance in infrared applications.

The window is uncoated, meaning it does not have any additional layers of material applied to its surface. While coatings can enhance certain properties of an optical component, such as reducing reflection or increasing transmission, an uncoated window can be advantageous in certain situations. For instance, it can be used in applications where the introduction of a coating might alter the optical properties of the system.

The window's flat design ensures that it does not distort the light passing through it, making it suitable for use in imaging systems, beam delivery, and other applications where maintaining the integrity of the light path is crucial.
