The OPB-40C04-10-5 is a 40 mm diameter N-BK7 round optical parallel flat window with a thickness of 4 mm, sourced from OptoSigma. This window is a type of flat window, designed with a base shape of a circle, making it suitable for a wide range of optical applications.
The window is made from N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. This material, also known as Schott glass, has a refractive index of approximately 1.5168 at a wavelength of 588 nm. The window's thin lens shape further enhances its optical performance.
Notably, this window is uncoated, meaning it does not have any additional layers applied to its surface. While coatings can enhance certain optical properties, an uncoated window can be advantageous in certain applications where specific coatings may interfere with the desired optical outcome.
