11-858 150 mm Dia. N-BK7 Precision Protective Flat Window; t=10 mm Uncoated

The 11-858 is a precision protective flat window offered by Edmund Optics, designed for applications demanding high-quality optical components. This window boasts a substantial 150 mm diameter, providing a generous aperture for a wide range of uses. With a thickness of 10 mm, it offers excellent rigidity and stability, making it suitable for more demanding environments.

The window is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties. N-BK7, also known as BK7, is a borosilicate crown glass with a low refractive index and low dispersion, making it an ideal material for various optical applications. This specific window is uncoated, offering bare glass performance, which may be desirable in certain applications where specific coatings could introduce unwanted effects.

The window's flat shape ensures minimal distortion, making it suitable for use as a protective cover or as an optical component in systems where minimal alteration of the light path is required. The uncoated nature of the window makes it versatile, as it can be used in a wide range of wavelengths, with the provided wavelength of 587.6 nm serving as a reference point.
