OPCFU-40C03-P 40 mm Dia. CaF2 Round Flat Window; t=3 mm Uncoated

The OPCFU-40C03-P is a 40 mm diameter Calcium Fluoride (CaF2) flat window, offered by OptoSigma. This window, with a thickness of 3 mm, is uncoated, making it suitable for use in ultraviolet and infrared laser applications.

The item is a circular window, a type of optical component that allows light to pass through while providing protection for the optical system. The flat shape of this window ensures that the light passing through remains undistorted.

The CaF2 material ID indicates that this window is made from Calcium Fluoride, a material known for its excellent transparency in the ultraviolet, visible, and infrared regions of the spectrum. This makes the OPCFU-40C03-P a versatile option for various laser applications.

The window's geometry is defined by its diameter and thickness. With a diameter of 40 mm, it provides a substantial aperture for light to pass through. The thickness of 3 mm ensures rigidity while minimizing optical distortion.

The window is uncoated, meaning it does not have any additional layers applied to its surface. This can be beneficial in applications where the user wants to avoid any potential interference from coating materials. However, it's important to note that uncoated windows may have higher surface reflections compared to coated ones.
