540-7251 25.4 mm Dia. Barium Fluoride Window; t=3 mm Uncoated

The 540-7251 is a high-quality optical window offered by EKSMA Optics, a leading vendor in the field of UV and IR optics. This window, designed for use in a wide range of applications, boasts a diameter of 25.4 mm and a thickness of 3 mm, making it a robust and reliable choice for various optical systems.

The window is made from Barium Fluoride (BaF2), a material with a Material ID of [baf2 cgdm]. This material is known for its excellent transparency in the ultraviolet (UV) region, making this window an ideal choice for applications that require UV transmission. The specified wavelength for this window is 265 nm, further emphasizing its suitability for UV applications.

The window features a flat, circular shape, which is designed to minimize optical distortions and ensure clear, undistorted transmission of light. The geometry of the window, including its diameter and thickness, has been carefully selected to provide a balance between strength, durability, and optical performance.

Notably, this window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where a natural, unaltered optical surface is required. However, for applications that require specific optical properties, such as enhanced reflectivity or transmissivity, additional coatings can be applied.
