220-0726M 75.0 mm Dia. N-BK7 Precision Round Window; t=12.7 mm Uncoated

The 220-0726M is a precision round window offered by EKSMA Optics, a leading vendor in the optical components industry. This window, designed for use with lasers, boasts a base shape of a flat circular disc, providing a reliable and robust solution for various optical applications.

The window has a diameter of 75.0 mm, making it suitable for use in systems that require larger optical components. The thickness of the window is 12.7 mm, providing sufficient structural integrity while minimizing optical distortion. The window is made of N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low refractive index and low dispersion. This material is sourced from Schott, a renowned glass manufacturer, ensuring high 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 advantageous in certain applications where the natural reflective properties of the glass are desired or where the environment is not conducive to coatings. However, users should be aware that uncoated windows can have higher reflectivity, which may affect the performance of some optical systems.

The window is classified as a thin lens, indicating that its thickness is significantly less than its diameter. This design ensures minimal optical distortion and provides excellent optical transmission.
