The 010-0216E is a Plano-Concave Window with a diameter of 25.4 mm, manufactured by EKSMA Optics. This window is a type of curved window, designed with a spherical shape and a base shape of a circle. The concave surface of the window has a radius of curvature (R1) of -800, and the effective focal length (EFL) is 1547.43. The window has a thickness of 6 mm at the edge.
The material used for this window is N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The window is uncoated, meaning it does not have any anti-reflective or other coatings applied to its surfaces. This can be beneficial in certain applications where the natural properties of the glass are desired.
The window is designed to operate at a wavelength of 588 nm. It is in stock and available for immediate purchase through the EKSMA Optics website, as indicated by the "weblink status" field in the item data.
