38-581 12.5mm Dia. x 20mm FL; YAG-BBAR Coated; Plano-Convex Lens YAG-BBAR 500-1100nm
This is a Plano-Convex Lens, type 38-581, sourced from the renowned optical components vendor, Edmund Optics. The lens boasts a diameter of 12.5mm and a focal length of 20mm, making it a compact yet powerful optical tool. The base shape is circular, ensuring uniform light distribution and minimal distortion.
The lens is made from the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability. The geometry of the lens is meticulously designed with a thickness of 1.4mm at the edge and 3.5mm at the center, providing a balanced structure for optimal performance. The lens's effective focal length (EFL) is 20mm, and the radius of curvature (R1) is 10.34mm, contributing to its superior light-bending capabilities.
The lens features a broadband anti-reflection coating, specifically YAG-BBAR, which is effective between 500-1100nm. This coating reduces surface reflections, enhancing the lens's transmission efficiency and overall performance. The coating is applied to both the front and back surfaces of the lens, ensuring optimal light transmission from all angles.
