39-538 50.8mm Dia. x 75mm FL; Uncoated; ZnSe Plano-Convex Lens

The 39-538 is a 50.8mm diameter, 75mm focal length plano-convex lens, sourced from Edmund Optics. This uncoated lens is made of ZnSe (Zinc Selenide) material, specifically identified as 'znse marple-1964'.

The lens's geometry includes a 2.39mm edge thickness and a 5.5mm center thickness. It has an inner radius of 0mm and an outer radius of 0mm, with a base shape of a circle. The lens's shape is spherical, and it is designed to operate at a wavelength of 10600nm.

The 39-538 is a type of spherical lens, and more specifically, a plano-convex lens. This type of lens has one side that is flat (planar), and the other side is curved (convex). This design allows for the concentration of light onto a single point, making it ideal for various applications such as imaging, beam shaping, and focusing.

The lens is currently in stock and available for purchase through the provided weblink. Please note that the lens is uncoated, which means it does not have any additional layers to protect it from environmental factors or to enhance its optical properties. This may affect its performance in certain applications, so it is essential to consider this factor when making your selection.
