LA0618-E 25.4 mm Dia. BaF2 Plano-Convex Lens; EFL=150mm 2-5µm

The LA0618-E is a Plano-Convex Spherical Lens with a diameter of 25.4 mm, manufactured by Thorlabs. This lens is designed for use with wavelengths of 4000 nm and features a focal length of 150 mm. The lens is made of Barium Fluoride (BaF2) and has an Anti-Reflection coating on both the front and back surfaces, specifically the tho ebaf2arc20005000 coating.

The lens's geometry includes a thickness of 2 mm at the edge and 3.2 mm at the center. The inner and outer radii are both 0 mm, and the lens's shape is spherical. The LA0618-E is available from Thorlabs and is currently in stock.

This lens is ideal for applications that require a high level of precision and clarity, such as imaging systems, beam shaping, and laser applications. Its BaF2 material makes it suitable for use in harsh environments, as it has a high damage threshold and is resistant to thermal shock. The Anti-Reflection coating ensures minimal loss of light and improved transmission, making it an excellent choice for applications that require high transmission and low loss.
