OPCF-25C03-P 25 mm Dia. CaF2 Round Flat Window; t=3 mm Uncoated

The OPCF-25C03-P is a 25 mm diameter Calcium Fluoride (CaF2) Round Flat Window, with a thickness of 3 mm, sourced from OptoSigma. This window is a type of optical component designed to allow light to pass through while minimally altering the light's path or intensity.

The window's base shape is circular, which is a common choice due to its symmetry and ease of integration into various optical systems. The geometry of the window includes a diameter of 25 mm and a thickness of 3 mm, providing a balance between strength, weight, and optical performance.

The material of this window is Calcium Fluoride (CaF2), which is known for its excellent transparency in both ultraviolet and infrared regions of the spectrum. This makes the OPCF-25C03-P suitable for applications that involve these wavelengths. The specific wavelength mentioned in the item data is 588 nm, which falls within the visible light spectrum.

The window is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in situations where the user wants to minimize reflections or other optical interactions. However, it's important to note that uncoated windows may not perform as well in extreme environments, such as high humidity or temperature fluctuations.
