220-0201E 25.4 mm Dia. N-BK7 Precision Round Window; t=6 mm Uncoated

The 220-0201E is a precision round window, boasting a diameter of 25.4 mm and a thickness of 6 mm. This window is fabricated from N-BK7, a popular glass type manufactured by Schott, known for its excellent optical properties and wide transmission range.

The window is designed in a flat configuration, which is ideal for applications that require minimal optical distortion. The base shape of the window is circular, making it suitable for a wide range of applications where a circular aperture is required.

The window is uncoated, which means it does not have any anti-reflective or other coatings. This can be beneficial in applications where the introduction of a coating could potentially alter the optical properties of the system. However, it's important to note that uncoated windows can have higher reflectivity at certain wavelengths, which could impact the performance of some systems.

This window is designed for use with a wavelength of 633 nm, making it suitable for a wide range of applications in the visible spectrum. The window is also designed with a thin lens shape, which can be beneficial in applications where a thin, lightweight optical element is required.

The window is sourced from EKSMA Optics, a reputable vendor known for their high-quality optical components. According to the vendor, the window is in stock and the associated web link is valid, providing users with confidence in the availability of this component.
