69-350 25.0mm Dia. x 150.0mm FL; Plano-Convex Lens Laser V-Coat 405nm
This is a 25.0mm diameter, 150.0mm focal length plano-convex lens, specifically designed for use with a 405nm wavelength. The lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock.
The lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The plano-convex geometry, where one side is flat and the other is curved, is ideal for applications that require a collimated beam. The lens has a center thickness of 3.5mm and an edge thickness of 2.49mm, providing a robust structure while maintaining a low profile.
The lens features a V-coat coating on both the front and back surfaces, specifically designed for laser applications at 405nm. This coating enhances the lens's durability and performance, reducing surface reflections and increasing transmission. The lens's effective focal length (EFL) is 150mm, and the back focal length (BFL) is 147.81mm, making it suitable for a wide range of optical systems.
