69-635 50.0mm Dia. x 250.0mm FL; Plano-Convex Lens Laser V-Coat 1064nm

This is a 50.0mm diameter by 250.0mm focal length plano-convex lens, specifically designed for use with a 1064nm 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 wide transparency range. The plano-convex geometry, where one side is flat and the other curved, is ideal for a variety of applications, particularly where a collimated beam is required.

The lens has a center thickness of 4.94mm and an edge thickness of 2.5mm, providing a robust structure while maintaining a relatively lightweight design. The front and back surfaces of the lens are coated with Edmund Optics' Las V-Coat 1064, a specialized coating that enhances the lens' performance in laser applications.

The coating reduces reflection and increases transmission, making it ideal for high-power laser applications. The lens' inner and outer radii are both 0mm, indicating a sharp curvature on the convex side. The lens' EFL (Effective Focal Length) is 250mm, which is the distance from the lens' principal point to the focal point when the lens is imaging an object at infinity.

This lens is currently in stock, making it a readily available option for those in need of a high-quality, plano-convex lens for their 1064nm laser applications.
