05Q20-NL 12.7 mm Dia. UVFS Parallel Optical Flat Window; t=3 mm Uncoated

The 05Q20-NL is a high-quality flat window from the renowned optical components manufacturer, MKS/Newport. This particular model boasts a diameter of 12.7 mm and a thickness of 3 mm, making it a versatile choice for various optical applications.

The window is made from UVFS material, specifically identified as UVFS Mal-1965 in the item data. This material is known for its excellent optical properties, making it suitable for use in environments where high light transmission and clarity are required. The window is uncoated, which means it does not have any additional layers of material applied to alter its optical properties. This can be beneficial in certain applications where a natural optical path is desired.

The 05Q20-NL is designed in the shape of a thin lens, which is a common choice for optical components due to its minimal impact on the optical path. The window's geometry is circular, a standard shape for optical components due to its symmetry and ease of integration into optical systems.

The window is designed to work optimally at a wavelength of 632.8 nm. This wavelength falls within the visible light spectrum, indicating that this window is suitable for use in applications involving visible light.
