VPW42 Dia:1.5in UVFS Vacuum Window; t=4mm Uncoated

The VPW42 Dia:1.5in UVFS Vacuum Window is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical equipment. This window is designed for use in vacuum environments and features a flat, circular shape with a diameter of 38.099999999999994 mm and a thickness of 4.04 mm.

The window is made from UVFS, a material with the Material ID "uvfs mal- 1965". This material is well-suited for applications involving ultraviolet light, as indicated by the "UV" in its name. The window's thickness and material make it an ideal choice for applications that require a balance of durability and transparency.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be advantageous in certain applications where a natural, unaltered optical path is desired. However, it's important to note that uncoated windows may have higher reflectivity than coated windows, especially at certain wavelengths.

The window is designed for use at a wavelength of 633 nm. This wavelength falls within the visible light spectrum, suggesting that this window could be used in applications involving visible light.

In terms of geometry, the window is shaped like a thin lens. This means it has slight curvature, which can affect the way light passes through it. However, the curvature is minimal, and the window is primarily designed for use as a flat, transparent barrier.
