45-570 40 mm Dia. UVFS Round Protective Flat Window; t=4 mm Uncoated

The 45-570 is a 40 mm diameter uncoated 1λ fused silica window, sourced from Edmund Optics. This window is designed for use as a flat protective window, featuring a base shape of a circle and a thin lens shape. The window has a thickness of 4 mm, providing sufficient protection while maintaining minimal optical distortion.

The material of this window is UVFS, also known as UV-grade fused silica, which is highly transmissive across a broad spectrum, including the ultraviolet region. This makes it an ideal choice for applications that require high transmission in the UV range, such as UV spectroscopy or UV imaging.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where coatings may introduce unwanted effects, such as spectral shifts or additional reflections. However, it's important to note that uncoated windows can have higher reflectivity, which may need to be considered in the overall system design.

The window is currently in stock and available for immediate purchase. For more information, including detailed specifications and purchasing options, please refer to the provided weblink.
