OPB-15S03-1-5 15 x 15 mm N-BK7 Square Optical Parallel Flat Window; t=3 mm Uncoated

The OPB-15S03-1-5 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of optical systems. This window features a square shape with dimensions of 15 x 15 mm, making it suitable for applications that require a compact, yet robust optical component.

The window is made from N-BK7, a popular optical glass known for its excellent optical properties. This material, also known as Schott BK7, offers a high refractive index and low dispersion, making it an ideal choice for a wide range of optical applications. The window has a thickness of 3 mm, providing a good balance between durability and light transmission.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be beneficial in applications where coatings may interfere with the optical performance, or where simplicity and cost-effectiveness are key factors. However, it's important to note that uncoated windows can reflect a small percentage of light, which may need to be considered in certain applications.

The window is classified as a flat window, meaning it has a flat surface on both sides. This is in contrast to curved windows, which have one or both surfaces curved. Flat windows are often used in applications where the optical path needs to be unaltered, such as in beam splitters or as protective windows.
