The 89-010 is a Plano-Convex Spherical Lens, a high-quality optical component designed for use in a wide range of applications. This lens, sourced from the renowned vendor Edmund Optics, boasts a diameter of 20.0mm and a focal length of 70.0mm, making it a versatile choice for many optical systems.
The lens is crafted from n-BK7 Schott, a popular optical glass known for its excellent optical properties and high transmittance in the visible spectrum. This material ensures superior image quality and minimal distortion.
The 89-010 features a Plano-Convex geometry, with a flat front surface and a curved back surface. The center thickness of the lens is 3.0mm, while the edge thickness is 1.59mm, providing a robust and durable design. The lens's inner and outer radii are 0mm, indicating a sharp curvature on the back surface.
The lens is coated with Edmund Optics' Las V-Coat 633, a broadband anti-reflection coating specifically designed for the 633nm wavelength. This coating reduces surface reflections, enhancing the lens's transmission and overall performance in laser applications.
