OPB-20C03-1-5 20 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-20C03-1-5 is a 20 mm diameter N-BK7 round optical parallel flat window with a thickness of 3 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 Schott, a popular material in the optical industry due to its excellent optical properties. It has a wavelength of 588 nm, which is within the visible light spectrum. The window's shape is defined as a thin lens, indicating its minimal thickness relative to its diameter, which contributes to its lightweight nature and ease of integration into optical systems.

Notably, this 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 applications where the natural properties of N-BK7 are desired, or where additional coatings may interfere with the system's performance.
