67-237 50mm Dia. x 250mm FL VIS 0° Coated; UV Plano-Convex Lens VIS 0° 425-675nm

This optical lens, offered by Edmund Optics, is a 50mm diameter, 250mm focal length plano-convex lens, designed for use within the visible light spectrum, specifically between 425-675nm. The lens is made from fused silica (mal-1965) and features a standard curvature coating on both the front and back surfaces, identified as 'edm vis-0 std curve'.

The lens's geometry includes a 4.24mm edge thickness and a 7mm center thickness. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the incident side. The lens's effective focal length (EFL) is 250mm, and the back focal length (BFL) is 245.21mm. The radius of curvature (R1) is 114.62mm.

This lens is a valuable addition to any optical system that requires a plano-convex lens within the specified wavelength range. Its high-quality fused silica material and standard curvature coating ensure reliable performance and durability. The lens's specifications make it suitable for a wide range of applications, from imaging and beam shaping to spectroscopy and metrology.
