LA6004 25.4 mm Dia. MgF2 Plano-Convex Lens; EFL=75mm Uncoated

The LA6004 is a plano-convex lens with a diameter of 25.4 mm, making it suitable for a wide range of optical applications. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components. The lens's base shape is circular, and it features a spherical geometry, which is a common choice for many optical systems due to its ease of manufacturing and use.

The LA6004 has an effective focal length (EFL) of 75mm, which is a crucial parameter in lens selection. This EFL value indicates that the lens will focus light to a point 75mm away from the lens if the incoming light is parallel. This property is essential in designing and simulating optical systems.

The lens is made from magnesium fluoride (MgF2), a material with a refractive index of 1.38 at 589.3 nm. This material is often used in optical applications due to its excellent transparency across a wide spectrum, including the visible and near-infrared regions. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.

The lens's geometry includes a thickness of 2mm at the edge and 5mm at the center. The inner and outer radii are 0, indicating a plano-convex lens, where one side is flat, and the other side is curved. The curvature of the lens is defined by a radius of 28.3mm.
