LC1120 N-BK7 Plano-Concave Lens; Dia:1 in; f=-100.0 mm Uncoated

The LC1120 N-BK7 Plano-Concave Lens is a high-quality optical component sourced from Thorlabs, a leading vendor in the field of optical components. This lens, with a diameter of 1 inch, is designed to bend light rays to a specific focal point, making it ideal for a wide range of optical applications.

The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The N-BK7 Schott material ensures high transmission and low dispersion, making it suitable for use across a broad spectrum of wavelengths, including the visible light spectrum.

The LC1120 features a plano-concave geometry, meaning one side of the lens is flat (plano), while the other side is curved inward (concave). This design allows the lens to diverge light, making it suitable for use in applications where light needs to be spread out over a larger area.

The lens has an effective focal length (EFL) of -100.0 mm, indicating that it is a diverging lens. The EFL is a critical parameter in lens selection, as it determines the degree of divergence or convergence of light rays passing through the lens.

The lens has a center thickness of 4 mm and an edge thickness of 5.6 mm. The inner and outer radii are 0 mm, indicating that the lens has a sharp edge. The back focal length (BFL) of the lens is -102.6 mm.

Please note that this lens is uncoated. Coatings are often applied to optical surfaces to enhance their performance by reducing reflection, increasing transmission, or altering the phase of the light. However, this lens is designed to operate without a coating.
