OPB-50S08-20-2 50 x 50 mm N-BK7 Square Optical Parallel Flat Window; t=8 mm Uncoated

The OPB-50S08-20-2 is a high-quality optical window from OptoSigma, designed to provide excellent performance in a variety of optical systems. This square window measures 50 x 50 mm and has a thickness of 8 mm, making it suitable for applications that require a robust and stable optical component.

The window is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and high damage threshold. N-BK7 is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal choice for broadband optical systems.

The window is uncoated, which means it does not have any anti-reflective or other coatings. While coatings can enhance the performance of an optical component in specific applications, an uncoated window can be a more cost-effective solution when such enhancements are not required.

The window is designed as a flat window, which means it has parallel surfaces. This is crucial in applications where maintaining the collimation or focusing of a beam is important. The window's flatness ensures that the beam will not be distorted as it passes through the window.
