561-6385 38.1 mm Dia. x 127 mm FL Plano-Convex Lens AR 10600nm
This 561-6385 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 38.1 mm and a thickness edge of 2.5 mm. The effective focal length (EFL) is 127 mm, and the first radius of curvature (R1) is 177.8 mm. The lens's inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other.
The lens is crafted from Zinc Selenide (ZnSe) material, identified as 'znse marple-1964' in the Material ID. This material is well-suited for use in the infrared (IR) spectrum, specifically at a wavelength of 10600nm, as indicated in the item data.
The lens is coated with 'eks znse ar 10600' on both the front and back surfaces. This anti-reflective (AR) coating is specifically designed to reduce reflections at the 10600nm wavelength, further optimizing the lens's performance in the IR spectrum.
