LC2265-A 12.7 mm Dia. N-SF11 Plano-Concave Lens; EFL=-15mm 350-700nm
The LC2265-A is a 12.7 mm diameter Plano-Concave Spherical Lens, designed for use in the ultraviolet to near-infrared spectrum, specifically between 350-700nm. This lens is sourced from Thorlabs, a leading global manufacturer of photonics components.
The lens is made from N-SF11 Schott glass, a high index material with excellent transmittance across a broad spectrum. The lens features a concave shape with a 12.7 mm diameter and a center thickness of 3 mm. The effective focal length (EFL) of this lens is -15mm, making it suitable for a variety of applications where a diverging lens is required.
The lens is coated with a broadband anti-reflection coating, denoted as 'tho a bbar' for both the front and back surfaces. This coating reduces surface reflections and increases transmission, enhancing the overall performance of the lens.
The item data also indicates that the lens has an inner radius of 0 and an outer radius of 0, suggesting a simple plano-concave design. This design is often used in applications such as beam expansion, collimation, and focusing.
