10BW40-30AR.14 25.4 mm Dia. N-BK7 Parallel Optical Flat Window; t=6 mm 430-700nm

This is a 10BW40-30AR.14 optical flat window, sourced from the renowned vendor MKS/Newport. The window, which is circular in base shape, has a diameter of 25.4 mm and a thickness of 6 mm, making it a robust and reliable component for various optical applications.

The window is made of N-BK7, a high-quality optical glass from Schott, which is known for its excellent optical properties and high damage threshold. This material is particularly suitable for applications in the visible spectrum, as indicated by the wavelength of 530 nm.

The window features a new AR-14 coating on both the front and back surfaces. This anti-reflective coating is designed to minimize reflection and maximize transmission in the spectral range of 430-700 nm. This makes the window ideal for use in systems where high transmission and low reflection are critical, such as in laser systems, beam delivery systems, and imaging systems.

The window is designed in the shape of a thin lens, which not only adds to its robustness but also allows it to be used in systems where precise focusing or collimation is required. Despite its thin lens shape, the window maintains a high level of optical quality, ensuring that it does not introduce any significant aberrations or distortions into the optical system.
