010-0110E 12.7 mm Dia. N-BK7 Plano-Concave Window; t=3mm Uncoated

This 010-0110E optical window, sourced from EKSMA Optics, is a curved window with a plano-concave base shape and a circular diameter of 12.7 mm. The window's thickness at the edge is 3 mm, and it is uncoated, offering a clear, unaltered view of the optical path.

The window's effective focal length (EFL) is 483.57 mm, making it suitable for applications that require a long focal length. The concave surface of the window has a radius of curvature (R1) of -250 mm, contributing to its focusing properties.

This window is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transmission range. It is designed to work optimally at a wavelength of 588 nm, making it suitable for applications in the yellow-orange part of the visible light spectrum.

Please note that this window is uncoated, meaning it does not have any anti-reflective or other surface coatings. This may result in some reflective loss at the air-glass interfaces, but it also ensures the window's durability and resistance to environmental factors.
