561-6258 25.4 mm Dia. x 254 mm FL Plano-Convex Lens AR 10600nm
This 561-6258 optical lens, sourced from EKSMA Optics, is a Spherical Lens of the Plano-Convex subtype. The lens has a base shape of Circular, with a diameter of 25.4 mm and a thickness edge of 2.5 mm. The effective focal length (EFL) of this lens is 254 mm, making it suitable for a variety of optical applications.
The lens is made from Zinc Selenide (ZnSe) material, specifically the ZnSe Marple-1964 variant. This material is known for its excellent transmission properties in the ultraviolet and infrared regions of the spectrum. The lens is designed to work optimally at a wavelength of 10600 nm.
The lens features Anti-Reflective (AR) coating on both the front and back surfaces. This coating, designated as 'eks znse ar 10600', is specifically designed to reduce reflection and increase transmission at the specified wavelength. The coating ensures that the lens performs optimally in its intended application, minimizing losses due to reflection.
