LE1076-A 50.8 mm Dia. N-BK7 Positive Meniscus Lens; EFL=100mm 350-700nm

The LE1076-A is a 50.8 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from the reputable vendor Thorlabs. This lens is specifically designed for use in the ultraviolet-visible (UV-Vis) spectrum, with a wavelength of 587.6 nm.

The lens is made from N-BK7, a high-quality borosilicate glass, which is known for its excellent optical properties and durability. The lens has a double-sided anti-reflection coating, denoted as 'tho a bbar' for both the front and back surfaces. This coating enhances transmission and reduces surface reflections, thereby improving the overall efficiency and performance of the lens.

The lens geometry includes a diameter of 50.8 mm, a thickness at the edge of 1.1 mm, and a center thickness of 9.7 mm. The Effective Focal Length (EFL) is 100 mm, and the Radius of Curvature (ROC) for the first surface (R1) is 30.3 mm, while for the second surface (R2) it is 65.8 mm. The Back Focal Length (BFL) is 88.8 mm. The lens does not have an Inner Radius or an Outer Radius.

This lens is suitable for use in a variety of applications, including but not limited to, imaging systems, beam shaping, and laser applications within the UV-Vis spectrum. With its robust construction, high-quality materials, and precise design, the LE1076-A is a reliable and efficient choice for your optical needs.
