011-0205E 25.4 mm Dia. N-BK7 Plano-Convex Window; t=6mm Uncoated

The 011-0205E 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 is characterized by its thickness at the center, which is 6 mm, and its effective focal length (EFL) of 580.29 mm. The curvature of the window is defined by a radius of 300 mm, which is typical for Plano-Convex windows. This curvature provides a slight focusing effect, which can be beneficial in certain optical systems.

The window is uncoated, meaning it does not have any anti-reflective or other coatings. This can be advantageous in some applications where the natural reflectivity of the glass surface is desired or where cost is a concern. However, it's important to note that uncoated windows can cause unwanted reflections and may not be the best choice for high-precision optical systems.

The window is designed to operate at a wavelength of 588 nm, making it suitable for applications that use light at this wavelength. This could include various scientific, industrial, or medical applications.
