LA6006 25.4 mm Dia. MgF2 Plano-Convex Lens; EFL=150.1mm Uncoated

The LA6006 is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use in the visible spectrum, specifically at a wavelength of 633 nm. The Plano-Convex geometry, characterized by a flat surface and a curved surface, is a common configuration in optical systems due to its ability to focus or collimate light.

The LA6006 has an effective focal length (EFL) of 150.1 mm, a critical parameter in lens selection. The EFL determines the distance at which the lens will focus parallel light, influencing the overall design and performance of the optical system. This lens, in particular, offers a long focal length, making it suitable for applications requiring a narrow field of view or high magnification.

The lens's geometry includes a thickness of 1.8 mm at the edge and 3.2 mm at the center. This asymmetry is a typical characteristic of Plano-Convex lenses, where the center is thicker to counteract spherical aberration, a common optical distortion. However, this lens does not have any anti-reflection coating, as indicated by the empty 'coating' field in the item data. This could lead to increased reflection at the lens surfaces, potentially impacting the system's overall efficiency.

The LA6006 is made of Magnesium Fluoride (MgF2), a material known for its excellent optical properties, including a high refractive index and low dispersion. This makes the lens suitable for high-precision applications where chromatic aberration, a common issue in optical systems, needs to be minimized.
