LA5012-E 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=150mm 2-5µm

The LA5012-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 its high-quality optical components. The Plano-Convex design features a flat front surface and a curved back surface, with a center thickness of 3.3 mm and an edge thickness of 2 mm. The Effective Focal Length (EFL) of this lens is 150 mm, making it suitable for a variety of applications that require precise focusing and imaging.

The lens is made from Calcium Fluoride (CaF2), a material with a high transmission rate in the infrared region, making it ideal for use in IR applications. The lens is coated with Thorlabs' ECaF2ARC20005000 coating on both the front and back surfaces, which enhances its durability and performance in the specified wavelength range.

The LA5012-E is a Spherical lens, meaning it has a spherical curvature on its surfaces. This curvature is defined by a radius of 65.1 mm on the curved surface. The lens does not have an inner or outer radius, indicating a consistent curvature across its surface.
