The 39-533 is a 25.4mm diameter, 75mm focal length plano-convex lens, sourced from Edmund Optics. This uncoated lens is made of ZnSe (Zinc Selenide) material, specifically identified as 'znse marple-1964'.
The lens's geometry is characterized by a 1.73mm edge thickness and a 2.5mm center thickness. The lens's effective focal length (EFL) is 75mm, and its radius of curvature (R1) is 105.2mm. The lens's inner and outer radii are both zero, indicating a plano-convex shape.
This lens is designed to operate at a wavelength of 10600nm, making it suitable for infrared (IR) applications. The lens's spherical shape ensures minimal optical aberrations, providing clear and accurate imaging.
Please note that this lens is uncoated, which may affect its performance in certain applications. Coatings can be applied to reduce surface reflections, increase transmission, and protect the lens from environmental factors. However, this lens, in its current form, is a cost-effective solution for applications where such coatings are not necessary.
