OPCFU-50C03-P 50 mm Dia. CaF2 Round Flat Window; t=3 mm Uncoated

The OPCFU-50C03-P is a 50 mm diameter Calcium Fluoride (CaF2) flat window, uncoated, with a thickness of 3 mm, manufactured by OptoSigma. This window is designed for use in ultraviolet and infrared laser applications, making it a versatile choice for a wide range of optical systems.

The window's base shape is circular, which is a common choice for applications requiring uniform light transmission. The geometry of the window includes a diameter of 50 mm and a thickness of 3 mm, providing a balance between strength and transparency. The uncoated surface allows for broadband transmission, making it suitable for use across a wide spectrum of wavelengths.

The material ID for this window is 'caf2 mal-1963', which identifies it as a Calcium Fluoride window. Calcium Fluoride is known for its excellent transmission properties in the ultraviolet, visible, and infrared regions of the spectrum. It also has a relatively low refractive index and a high Abbe number, making it a popular choice for a variety of optical applications.

The window is designed with a shape similar to a thin lens, although it does not have any focusing power. This shape is often used in optical systems where a flat, transparent element is required.

Please note that the window is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors. This may affect its performance in certain applications, so it's important to consider the specific requirements of your system when choosing an optical window.
