561-6257 25.4 mm Dia. x 200 mm FL Plano-Convex Lens AR 10600nm

This is a Plano-Convex lens, a type of spherical lens with a flat surface on one side and a curved surface on the other. The lens has a diameter of 25.4 mm and a focal length of 200 mm, making it suitable for a wide range of optical applications. The lens is made from Zinc Selenide (ZnSe), a material with excellent transmission properties in the ultraviolet and infrared regions of the spectrum.

The lens features an anti-reflective (AR) coating on both surfaces, specifically designed for a wavelength of 10600nm. This coating helps to reduce unwanted reflections and increase the amount of light transmitted through the lens, improving the overall performance of the optical system. The coating is applied by EKSMA Optics, a leading vendor in the field of optical components, and is identified as 'eks znse ar 10600'.

The lens has a thickness of 2.5 mm at the edge, and the curvature of the convex surface is defined by a radius of 280 mm. The lens does not have an inner radius or an outer radius, indicating that it is a simple plano-convex lens without any additional features.

This lens is available from EKSMA Optics and is currently in stock, according to the vendor's website. The item data also provides a link to the vendor's website for more information and to check the current availability and pricing.
