LA6002 25.4 mm Dia. MgF2 Plano-Convex Lens; EFL=50.1mm Uncoated

The LA6002 is a Plano-Convex lens with a diameter of 25.4 mm, sourced from the reputable optical components manufacturer, Thorlabs. This lens is designed for use in the visible spectrum, with a specified wavelength of 633 nm. The Plano-Convex geometry, 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 50.1 mm, which is a measure of the lens's ability to focus light. This value is calculated by taking the distance from the center of the lens to the point where the light rays converge, divided by the lens's diameter. A longer EFL indicates that the lens will produce a narrower, more focused beam of light.

The LA6002 is made from Magnesium Fluoride (MgF2), a material known for its excellent optical properties. It has a high transparency in the visible and near-infrared regions of the spectrum, making it suitable for a wide range of applications. The lens is uncoated, meaning it does not have any additional layers applied to its surface to enhance its optical properties.

The lens has a thickness of 2 mm at the edge and 6.9 mm at the center. The curvature of the lens is defined by a radius of 18.9 mm. The inner and outer radii are both 0, indicating that the lens does not have any peripheral features such as threads or flanges.

According to the vendor's website, the LA6002 is currently in stock, ensuring quick delivery for those who need it. The website also provides further technical specifications and application notes for this lens, which can be valuable resources for those considering this product.
