WNA5005 50mm Dia. Sodium Chloride Round Window; t=5mm Uncoated

The WNA5005 is a 50mm diameter flat window made of Sodium Chloride, sourced from Knight Optical. This uncoated window boasts a thickness of 5mm, making it a robust and reliable option for various applications. The window is designed in a circular base shape, which is a common choice due to its uniform stress distribution and minimal edge effects.

The window's geometry is defined by its 50mm diameter, providing a substantial aperture for light transmission. The 5mm thickness, on the other hand, ensures structural integrity without compromising optical performance. The window is categorized as a thin lens, indicating its minimal optical power and negligible curvature, making it ideal for applications where minimal distortion is required.

The material of this window is identified as UVFS MAL-1965, a specific type of Sodium Chloride known for its excellent optical properties and durability. The window is designed to operate at a wavelength of 633nm, making it suitable for a wide range of applications, including laser systems and optical metrology.

Notably, this window is uncoated, meaning it does not have any anti-reflective or other surface treatments. While this may result in higher reflective losses, it also means the window is less susceptible to damage from environmental factors, making it a practical choice for harsh environments.
