561-6253 25.4 mm Dia. x 76.2 mm FL Plano-Convex Lens AR 10600nm
This 561-6253 optical lens, sourced from EKSMA Optics, is a Spherical Lens of the Plano-Convex subtype, designed with a Circular base shape. The lens boasts a diameter of 25.4 mm and a thickness edge of 2.5 mm, making it a compact and efficient optical solution. The effective focal length (EFL) of this lens is 76.2 mm, and it has a front radius (R1) of 106.68 mm. The lens does not have an inner radius, and the outer radius is also not specified, indicating a simple, straightforward design.
The lens is made from Zinc Selenide (ZnSe), a material with the material ID 'znse marple-1964'. This material is known for its excellent transmission properties in the ultraviolet (UV) and infrared (IR) regions of the spectrum, making this lens suitable for applications in these wavelength ranges.
The lens is coated with 'eks znse ar 10600' on both the front and back surfaces. This anti-reflection (AR) coating is specifically designed to reduce reflection at the 10600nm wavelength, further enhancing the lens's performance in IR applications.
