011-0215E 25.4 mm Dia. N-BK7 Plano-Convex Window; t=6mm Uncoated

The 011-0215E is a Plano-Convex Window with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This window is manufactured by EKSMA Optics, a renowned vendor known for their high-quality optical components. The window is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties and high damage threshold.

The window's geometry features a thickness of 6 mm at the center, providing a good balance between strength and light transmission. The curvature of the window is spherical, with a radius of 1000 mm, resulting in an effective focal length (EFL) of 1934.29 mm. This curvature can help to reduce spherical aberration in optical systems.

The window is uncoated, which means it does not have any anti-reflective or other coatings. This can be beneficial in some applications where coatings may not be desired or necessary. However, it's important to note that uncoated windows can have higher reflective losses, especially at larger angles and for shorter wavelengths.

The window is designed to operate at a wavelength of 588 nm, making it suitable for applications that use this wavelength. This could include applications in spectroscopy, laser systems, or other optical instruments.
