89-014 5.0mm Dia. x 7.5mm FL; Plano-Convex Lens Laser V-Coat 785nm
The 89-014 is a 5.0mm diameter, plano-convex spherical lens with a 7.5mm focal length, specifically designed for use with a 785nm wavelength. This lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-sf11 Schott, a high-index glass material with excellent optical properties. It has a planar surface on one side and a convex surface on the other, with a center thickness of 1.9mm and an edge thickness of 1.34mm. The lens's design ensures a large numerical aperture, making it suitable for a wide range of applications.
The 89-014 features a laser-optimized V-coat coating on both the front and back surfaces. This coating is specifically designed to enhance the lens's performance in laser applications, reducing reflections and improving transmission. The coating is 785nm-specific, ensuring optimal performance at this wavelength.
The lens's geometry is carefully designed to provide superior optical performance. The inner and outer radii are 0, and the lens has a 5.89mm radius of curvature on the convex surface. The back focal length is 6.43mm, providing a long working distance and allowing for easy integration into optical systems.
