561-6122 12.7 mm Dia. x 25.4 mm FL Plano-Convex Lens AR 10600nm

This 561-6122 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 12.7 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 25.4 mm, which is a crucial factor in determining its optical performance.

The lens's geometry is further defined by its inner and outer radii, both of which are 0 mm in this case. However, the first radius of curvature (R1) is 35.56 mm, indicating a slightly curved design.

The lens is crafted from Zinc Selenide (ZnSe) material, identified as 'znse marple-1964' in the Material ID. This material is known for its excellent optical properties, making it suitable for various applications.

The lens is designed to operate at a wavelength of 10600 nm, which is in the infrared region of the spectrum. It is coated with 'eks znse ar 10600' on both the front and back surfaces, which is an anti-reflective coating specifically designed for this wavelength. This coating enhances the lens's performance by reducing unwanted reflections and increasing transmission.
