LC2969 6 mm Dia. N-SF11 Plano-Concave Lens; EFL=-6mm Uncoated
The LC2969 is a Spherical Lens with a Plano-Concave base shape and a circular design, sourced from the reputable vendor Thorlabs. This lens has a diameter of 6 mm and a center thickness of 1.5 mm, making it a compact and practical choice for various applications.
The effective focal length (EFL) of the LC2969 is -6 mm, which indicates that it is a diverging lens. This property is further emphasized by its inner radius of 0 mm and outer radius of 0 mm, both of which are typical for plano-concave lenses.
The lens is made of n-SF11 Schott, a high-index glass with excellent optical properties. This material is particularly suitable for applications that require high dispersion or high Abbe number. The lens is uncoated, which means that it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The LC2969 operates at a wavelength of 587.6 nm, which is within the visible light spectrum. This makes it suitable for applications that involve visible light, such as imaging, beam shaping, or light manipulation.
