47-230 50 mm Dia. UVFS Round Protective Flat Window; t=4 mm Uncoated

The 47-230 is a 50 mm diameter uncoated 1λ Fused Silica Window, sourced from Edmund Optics. This window is designed as a flat protective component, featuring a base shape of a circle for versatile application. The geometry of this window is defined by a 50 mm diameter and a thickness of 4 mm, ensuring robustness and durability.

The material of this window is UVFS, also known as Mal-1965, which is a type of fused silica. This material is chosen for its excellent transmission properties, making it suitable for a wide range of applications, particularly those involving ultraviolet light. The wavelength for this specific window is 587.6 nm, which falls within the visible light spectrum.

The window is shaped as a thin lens, which is a type of lens with a very small focal length compared to its diameter. This shape allows the window to be used in various optical systems without significantly altering the path of light.

Notably, this window is uncoated. Coatings are often applied to optical components to enhance their performance, such as improving transmission, reducing reflection, or adding specific wavelength selectivity. However, this window is left uncoated, which may be desirable for certain applications where a specific coating is not required or could potentially introduce unwanted effects.
