69-575 25.0mm Dia. x 300.0mm FL; Plano-Convex Lens Laser V-Coat 980nm
This is a 25.0mm diameter, plano-convex lens with a focal length of 300.0mm, specifically designed for use with a 980nm wavelength. The lens is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high homogeneity. The plano-convex geometry, where one side is flat and the other is curved, is ideal for a wide range of applications, particularly where a collimated beam is required.
The lens features a laser-optimized V-coat coating on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance in laser applications, reducing reflections and improving transmission. The coating is compatible with a 980nm wavelength, ensuring optimal performance in its intended use.
The lens has a center thickness of 298.02mm and an edge thickness of 2.5mm. The inner and outer radii are both 0mm, indicating a sharp transition from the flat to the curved surface. The lens' effective focal length (EFL) is 300mm, a common choice for applications requiring a long focal length.
