39-393 25 mm Dia. Zinc Selenide Protective Flat Window; t=5 mm Uncoated

The 39-393 is a 25 mm diameter Zinc Selenide (ZnSe) protective flat window with a thickness of 5 mm, uncoated and sourced from Edmund Optics. This window is a type of optical element, specifically a flat window, designed for use in various optical systems to protect the more sensitive components from environmental factors such as dust, dirt, or moisture, while minimally affecting the light path.

The window's base shape is circular, a common design for such components due to its ease of integration and alignment in optical systems. The geometry of the window is defined by its diameter and thickness. With a diameter of 25 mm, it provides a decent aperture for light to pass through while maintaining a compact form factor. The thickness of 5 mm, on the other hand, offers sufficient structural rigidity while also minimizing potential distortions due to the window's self-weight.

The material of the window is Zinc Selenide (ZnSe), a popular choice in optical systems due to its excellent transparency in the infrared region of the spectrum. This makes it suitable for applications where infrared transmission is critical, such as thermal imaging, night vision, or other similar systems.

The 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 certain applications where the natural properties of the material are desired, or where cost considerations are a factor. However, it may also mean that the window is more susceptible to environmental factors such as scratches or contaminants, which could affect its performance over time.

The window is currently in stock and can be purchased directly from the vendor's website.
