CAW18 40 mm Dia. Calcium Fluoride Parallel Optical Flat Window; t=3 mm Uncoated

The CAW18 is a high-quality optical window, designed and manufactured by MKS/Newport. This window is a circular flat type, with a diameter of 40 mm and a thickness of 3 mm, making it a versatile and robust option for various optical applications.

The window is made of Calcium Fluoride (CaF2), a material with the Mal-1963 ID, which is known for its excellent optical properties. It is particularly suitable for use with a wavelength of 632.8 nm, making it an ideal choice for applications that require high transmission in the visible spectrum.

The window is uncoated, which means it does not have any additional layers applied to its surface. This can be beneficial in applications where the natural properties of the material are desired, or where the addition of a coating could introduce unwanted complexity or cost.

The window is designed in the shape of a thin lens, which can be beneficial in applications where a flat surface is required, or where the window needs to be as thin as possible to minimize optical distortion.

According to the vendor, the window is currently in stock and can be shipped immediately. Further information, including detailed specifications and purchasing options, can be found on the MKS/Newport website.
