The NC-W-38.1-5 is a flat window type optical element, sourced from Alkor Technologies, with a circular base shape and a diameter of 38.1 mm. This window is designed to be thin, similar to a lens, and is made of Sodium Chloride (NaCl), also known as common salt, with the material ID UVFS MAL-1965.
The window has a thickness of 5 mm and is uncoated, meaning it does not have any additional layers to alter its optical properties. It is designed to work with a wavelength of 633 nm, which is within the visible light spectrum.
This window is available for purchase and more information can be found on the vendor's website, including its current stock status. The NC-W-38.1-5 is a reliable and versatile optical component, suitable for a wide range of applications that require a flat window with these specific dimensions and material properties.
