OPB-25C02-P 25 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=2 mm Uncoated

The OPB-25C02-P is a 25 mm diameter N-BK7 round optical parallel flat window with a thickness of 2 mm, sourced from OptoSigma. This uncoated optical component is designed for use in various applications that require a flat window.

The window is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. It is a borosilicate crown glass known for its low dispersion and high Abbe number, making it an ideal choice for applications that require high image quality and minimal chromatic aberration.

The window's geometry is circular, with a diameter of 25 mm and a thickness of 2 mm. The thin lens shape of the window ensures minimal optical distortion and a wide field of view. The uncoated surface of the window allows for maximum light transmission, making it suitable for applications where high transmittance is required.

The window is designed for use at a wavelength of 588 nm, but it can be used across a broader spectrum depending on the specific requirements of the application. The window's flat shape ensures parallelism of the light rays, making it suitable for use in laser applications, beam shaping, or any application that requires a flat, undistorted optical surface.
