LA0978-E 25.4 mm Dia. BaF2 Plano-Convex Lens; EFL=500mm 2-5µm

The LA0978-E is a 25.4 mm diameter Plano-Convex lens made of Barium Fluoride (BaF2) with an effective focal length (EFL) of 500mm, specifically designed for use in the 2-5µm wavelength range. This lens is sourced from Thorlabs, a leading global manufacturer of photonics equipment.

The lens features a plano-convex geometry, where one side is flat (plano) and the other side is curved (convex). The convex side has a radius of curvature (R1) of 228.3mm, while the inner and outer radii are both zero, indicating a flat inner and outer surface. The lens has a thickness of 2mm at the edge and 2.4mm at the center.

The LA0978-E is made of BaF2, a material known for its excellent transmission properties in the infrared region. The lens is coated with Thorlabs' EBAF2ARC20005000 coating on both the front and back surfaces, which further enhances its performance in the 2-5µm wavelength range.

This lens is a Spherical lens, meaning it has a spherical surface. The spherical shape ensures a high degree of optical accuracy and minimal aberration. The lens is designed for use in various applications, including but not limited to, infrared spectroscopy, thermal imaging, and other applications that require high-quality lenses in the 2-5µm wavelength range.
