The 87-986 is a high-quality aspheric lens, sourced from the renowned optical vendor, Edmund Optics. This lens is characterized by its 10mm diameter and a numerical aperture (NA) of 0.5, making it suitable for a wide range of applications. The lens is fabricated from UV fused silica, a material known for its excellent transparency across the ultraviolet, visible, and near-infrared spectra.
The lens's geometry is meticulously designed, featuring an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 2.77mm. The effective focal length (EFL) is 10mm, and the radius of curvature (R1) is 4.585mm. The lens's back focal length (BFL) is 5.89mm, and its thickness at the center is 6mm. The lens's aspheric shape is defined by its conic constant (k1) of -0.632906.
The 87-986 lens comes with a broadband anti-reflection coating, specifically designed for the visible spectrum (425-675nm). This coating ensures high transmission and low reflectance across the specified wavelength range, enhancing the lens's performance in various applications.
