OPB-20S03-20-2 20 x 20 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-20S03-20-2 is a high-quality optical window from OptoSigma, designed for use in a wide range of optical systems. This specific model features a square shape with dimensions of 20 x 20 mm and a thickness of 3 mm, making it suitable for applications that require a compact, yet robust optical component.

The window is made from N-BK7, a popular glass type known for its excellent optical properties. N-BK7, also known as BK7, is a borosilicate crown glass that offers low dispersion and high transmission in the visible spectrum, making it an ideal choice for many optical applications. The specific N-BK7 used in this window is sourced from Schott, a leading manufacturer of optical glass, ensuring a high level of quality and consistency.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in applications where such coatings are not required or desirable, such as when the window is used as a protective barrier or in situations where the natural reflectivity of the glass surface is desired.

The window is designed to be paralleled, meaning its two surfaces are precisely parallel to each other. This is crucial in many optical applications where precise alignment and minimal distortion are required. The window's flat design further enhances its suitability for such applications.
