63-207 20 mm Dia. Calcium Fluoride Protective Flat Window; t=2 mm Uncoated

The 63-207 is a 20 mm diameter Calcium Fluoride (CaF2) protective flat window, with a thickness of 2 mm and no coating. This window is sourced from Edmund Optics, a reputable vendor in the optical industry.

The window is designed as a flat window, which is a type of optical window that does not alter the path of light. It is circular in base shape, making it suitable for a wide range of applications. The window's geometry, including its 20 mm diameter and 2 mm thickness, is designed to provide optimal performance while maintaining a compact profile.

The window is made of Calcium Fluoride, a material with the ID caf2 mal-1963. This material is known for its excellent optical properties, including a high transmission rate across a wide range of wavelengths. The window is designed to operate at a wavelength of 587.6 nm, making it suitable for applications that require high-transmission at this wavelength.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where coatings may introduce unwanted reflections or other optical effects. However, it is important to note that uncoated windows may be more susceptible to environmental factors, such as dirt, dust, and moisture, which can affect their performance.
