89-048 5.0mm Dia. x 7.5mm FL; Plano-Convex Lens Laser V-Coat 1550nm
The 89-048 is a Plano-Convex spherical lens, a type of optical component characterized by its single curved surface and a flat surface on opposite sides. This lens, sourced from Edmund Optics, has a diameter of 5.0mm and a focal length of 7.5mm, making it suitable for a variety of applications that require precise focusing and beam shaping.
The lens is made from n-SF11 Schott, a high-index glass with excellent optical properties. This material is known for its low auto-fluorescence, making it ideal for use in laser applications. The lens has a thickness of 1.34mm at the edge and 1.9mm at the center, providing robustness and durability.
The 89-048 features a V-coat designed for 1550nm, a common wavelength for optical communications and other applications. This coating is applied to both the front and back surfaces of the lens, enhancing its performance in terms of transmission, reflection, and scattering. The coating is designed to be laser-friendly, ensuring minimal loss of energy and optimal beam propagation.
