The OPB-40C04-1-5 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, which is a common choice for applications requiring a broad field of view.

The window is made of N-BK7, a popular glass type in the optical industry, known for its excellent optical properties and versatility. This specific model is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in applications where the natural properties of the glass are desired.

The window is designed to be thin, with a shape similar to a thin lens. This makes it ideal for use in applications where space is limited, or where the window needs to be as unobtrusive as possible.
