LA6009 25.4 mm Dia. MgF2 Plano-Convex Lens; EFL=500mm Uncoated

The LA6009 is a plano-convex 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 shape, where one side is flat and the other is curved, is a common configuration in optical systems due to its ability to focus light efficiently.

The lens has an effective focal length (EFL) of 500 mm, which is a measure of how strongly it converges or diverges light. A longer focal length, like that of the LA6009, results in a narrower angle of light convergence, making it suitable for applications that require a more telecentric or magnified view.

The LA6009 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 ideal for applications that require high-quality imaging or light manipulation, such as microscopy, beam shaping, or laser applications.

Notably, this lens is uncoated. While coatings can be applied to lenses to reduce reflection, increase transmission, or protect the lens surface, an uncoated lens can be advantageous in certain applications where specific coating properties are not required.
