39-519 12.7mm Dia. x 12.7mm FL; Uncoated; ZnSe Plano-Convex Lens

The 39-519 is a 12.7mm diameter x 12.7mm focal length uncoated ZnSe plano-convex lens, available from Edmund Optics. This lens is part of their extensive catalog of optical elements, sourced from various vendors worldwide.

The lens is spherical in shape, with a base shape of circular. The geometry of the lens includes a diameter of 12.7mm, a thickness at the edge of 1.83mm, and a thickness at the center of 3mm. The effective focal length (EFL) is 12.7mm, and the radius of curvature (R1) is 17.81mm. The lens does not have an inner or outer radius.

The lens is made of ZnSe (Zinc Selenide) material, identified as 'znse marple-1964'. This material is known for its excellent transmission in the infrared region, making it suitable for applications such as IR spectroscopy, thermal imaging, and night vision systems.

The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. While this may result in a lower transmission rate and increased susceptibility to environmental factors, it also means that the lens is more cost-effective and suitable for applications where such enhancements are not necessary.

The lens is currently in stock, according to the vendor's website. For more information, including pricing and availability, please refer to the provided weblink.
