69-512 50.0mm Dia. x 200.0mm FL; Plano-Convex Lens Laser V-Coat 785nm
This is a 69-512 Plano-Convex Lens, a high-quality optical component sourced from Edmund Optics. The lens has a diameter of 50.0mm and a focal length of 200.0mm, making it suitable for a wide range of applications that require precise optical focusing.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. This material ensures high transmittance across a broad spectrum, making it ideal for use in laser applications.
The lens features a Plano-Convex geometry, where one side is flat (Plano) and the other side is curved (Convex). This geometry provides a large, flat surface for easy integration into optical systems while also offering a high degree of focusing power.
The lens is coated with Edmund Optics Laser V-Coat 785, a broadband anti-reflection coating designed for use with 785nm lasers. This coating reduces surface reflections, enhancing the overall transmission of the lens and improving the performance of the optical system.
The coating is applied to both the front and back surfaces of the lens, ensuring optimal performance from all angles. The coating also provides excellent environmental stability, ensuring the lens maintains its performance even in challenging conditions.
