W-BKS010 50 mm Dia. N-BK7 Standard Flat Window; t=3mm Uncoated

The W-BKS010 is a 50 mm diameter Flat Window, part of the N-BK7 Standard series from Ross Optical. This window is designed for general-purpose use and is a popular choice for various optical applications due to its versatility and high-quality performance.

The window is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion, which reduces the risk of thermal stress and distortion. The N-BK7 Schott variant used in this window is particularly renowned for its high homogeneity and low optical dispersion, making it ideal for applications that require high light transmission and precise optical path control.

The window has a thickness of 3mm, providing a good balance between mechanical strength and optical performance. It is uncoated, meaning it does not have any anti-reflective or other surface coatings. This can be advantageous in certain applications where a broad spectral range is required, as coatings can sometimes introduce unwanted spectral selectivity. However, it's important to note that uncoated windows can have higher reflectivity at certain wavelengths, which may need to be considered in the overall system design.

The window is circular in base shape, making it compatible with a wide range of optical components and systems. It is designed using a Thin Lens geometry, which is a simplified model assuming the window has negligible thickness compared to its diameter. This model is often used in preliminary optical design stages and can be refined later with more detailed models if necessary.
