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

The OPCFU-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 uncoated, making it suitable for use in ultraviolet and infrared laser applications.

The window is of the 'flat window' subtype, which means it is designed to provide a clear view of the target object without any optical distortion. The base shape is circular, which is a common choice for applications requiring a wide field of view.

The material ID for this window is 'caf2 mal-1963', indicating that it is made of Calcium Fluoride, a material known for its excellent optical properties, including high transparency and a wide transmission range. The window is designed to operate at a wavelength of 588 nm, which is in the visible light spectrum.

The window has a 'thin lens' shape, which means it has a very small curvature, if any. This makes it ideal for applications where minimal optical power is required. The window is uncoated, meaning it does not have any additional layers to enhance its optical properties. This can be beneficial in applications where the coating might interfere with the laser's performance.
