39-531 25.4mm Dia. x 35mm FL; Uncoated; ZnSe Plano-Convex Lens

The 39-531 is a 25.4mm diameter, 35mm 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 2.03mm edge thickness and a 3.7mm center thickness, with no inner or outer radius specified, indicating a flat-to-curved surface configuration. The effective focal length (EFL) is 35mm, and the lens has a spherical shape.

This lens is designed to operate at a wavelength of 10600nm, making it suitable for various applications in the infrared spectrum. The lack of coating on this lens may result in higher scattering and lower transmission compared to coated alternatives, but it can provide a cost-effective solution in situations where such trade-offs are acceptable.

Overall, the 39-531 25.4mm Dia. x 35mm FL; Uncoated; ZnSe Plano-Convex Lens is a specialized optical component, well-suited for applications in infrared spectroscopy, thermal imaging, and other domains requiring lenses optimized for longer wavelengths.
