The 39-524 is a 12.7mm diameter, 25.4mm 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 includes a 1.93mm thickness at the edge, increasing to 2.5mm at the center. The lens's design features a spherical shape with a 35.63mm radius on the curved side. The inner and outer radii are both zero, indicating a plano surface on the opposite side.
The lens is intended for use with a wavelength of 10600nm. It's important to note that this lens does not have any coating, which may affect its performance in certain applications.
This lens is currently in stock and available for immediate purchase from the Edmund Optics website.
