The NC-W-25.4-3 is a flat window optical element with a diameter of 25.4 mm and a thickness of 3 mm. This window is sourced from Alkor Technologies, a reputable vendor in the optical industry. The window is made of sodium chloride (NaCl), a material with the UVFS MAL-1965 material ID, which is known for its excellent optical properties.
The window is designed in a thin lens shape, which is ideal for applications that require minimal optical distortion. It is uncoated, meaning it does not have any additional layers of material to enhance or alter its optical properties. This makes it suitable for applications where the natural optical properties of the NaCl material are desired.
The window is designed to work with a wavelength of 633 nm, making it suitable for a wide range of optical applications. It is currently in stock and available for purchase, as indicated by its valid weblink status.
