LA0835-E 25.4 mm Dia. BaF2 Plano-Convex Lens; EFL=50mm 2-5µm

The LA0835-E is a Plano-Convex lens with a diameter of 25.4 mm, designed for use in the 2-5 µm wavelength range. This lens is sourced from Thorlabs, a reputable vendor known for their high-quality optical components.

The lens is made from BaF2, a material with a refractive index of 1.483 at 20°C, making it suitable for a wide range of optical applications. The lens has an effective focal length (EFL) of 50 mm, providing a moderate level of magnification.

The LA0835-E features a front and back coating of tho ebaf2arc20005000, which enhances its performance in the specified wavelength range. The lens has a thickness of 2 mm at the edge and 5.9 mm at the center, providing a good balance between durability and optical performance.

The lens geometry is spherical, with a radius of curvature of 22.8 mm for the convex surface. The inner and outer radii are both 0, indicating a planar surface on the other side. This lens is a great choice for applications that require a high-quality, broadband optical component.
