220-0403E 38.1 mm Dia. N-BK7 Precision Round Window; t=10 mm Uncoated

The 220-0403E is a precision round window, boasting a diameter of 38.1 mm and a thickness of 10 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 of the flat variety, designed for use in applications where a flat optical surface is required. The geometry of the window is defined by its diameter and thickness, with the former determining the size of the optical aperture and the latter influencing the window's rigidity and stress distribution.

This 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 reflectivity of the glass surface is desired or where the introduction of a coating could compromise the window's optical performance.

The window is classified as a thin lens, indicating that its thickness is significantly less than its diameter. This is often desirable in optical systems where minimizing the thickness of components can help reduce aberrations and improve overall system performance.

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 ready for immediate dispatch.
