OPB-60C10-4-5 60 mm Dia. N-BK7 Round Optical Parallel Flat Window; t=10 mm Uncoated

The OPB-60C10-4-5 is a high-quality optical window offered by OptoSigma. This window is designed for use in a variety of optical systems, providing a clear, flat surface for light to pass through.

The window is made from N-BK7, a type of borosilicate glass that is known for its excellent optical properties. N-BK7, also known as BK7, is a common material in optical systems due to its low dispersion and high transmission in the visible spectrum. The window has a diameter of 60 mm and a thickness of 10 mm, making it suitable for use in a wide range of applications.

The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in some applications where a natural, unaltered surface is desired. However, it's important to note that uncoated surfaces can reflect up to 4% of incident light, which may need to be taken into account in certain system designs.

The window is designed in a flat configuration, which means it does not have any curvature. This is ideal for applications where a flat, undistorted view is required. The window is also thin, which helps to minimize weight and bulk while maintaining structural integrity.
