69-589 6.0mm Dia. x 21.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm
The 69-589 is a Plano-Convex spherical lens, characterized by its 6.0mm diameter and 21.0mm focal length. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry, and is designed to work optimally with a wavelength of 1064nm.
The lens is fabricated from N-BK7 Schott, a popular optical crown glass due to its excellent homogeneity, low optical dispersion, and high transmittance in the visible and near-infrared regions. The lens's geometry includes a 1.0mm edge thickness and a 1.42mm center thickness, contributing to its robustness and optical performance.
The 69-589 lens features a front and back coating of EDM Las V-Coat 1064, a proprietary coating developed by Edmund Optics. This coating enhances the lens's performance by reducing surface reflections, increasing transmission, and providing protection against environmental factors. The coating is specifically designed for 1064nm, ensuring optimal performance within this wavelength range.
