47-681 10 mm Dia. Calcium Fluoride Protective Flat Window; t=1.5 mm Uncoated

The 47-681 is a 10 mm diameter Calcium Fluoride (CaF2) protective flat window, uncoated, with a thickness of 1.5 mm. This window is sourced from Edmund Optics, a reputable vendor known for its high-quality optical components.

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 shape, making it suitable for a wide range of applications. The window is made of Calcium Fluoride, a material with a high transmission range, making it ideal for use in the ultraviolet, visible, and infrared regions of the spectrum.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in certain applications where a specific coating is not required or desired. However, it is important to note that uncoated windows may be more susceptible to environmental factors such as dust, moisture, and scratches.

The window has a wavelength of 587.6 nm, which is in the yellow-orange region of the visible spectrum. This specific wavelength is often used in various applications, including spectroscopy and laser systems.

The window is shaped as a thin lens, which is a lens with a thickness that is significantly less than its diameter. This shape is often used in applications where a thin, lightweight lens is required.
