112-1211E 25.4 mm Dia. x -100 mm FL; Uncoated; Plano-Concave Lens
The 112-1211E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens is characterized by its concave shape, which is thinner at the center and thicker at the edges. The base shape of this lens is circular, and it has a diameter of 25.4 mm.
The lens has a center thickness of 3 mm and an edge thickness of 4.7 mm. The effective focal length (EFL) of this lens is -100 mm, indicating that it diverges light. The radius of curvature (R1) is -47.6 mm, and the inner and outer radii are 0 mm, indicating that the lens is plano on both sides.
This lens is made from UVFS Mal-1965, a material with a wavelength of 355 nm. The lens does not have any coating, as indicated by the empty 'coating' parameter in the item data.
The lens is in stock and available for purchase. For more information, please refer to the vendor's website at http://eksmaoptics.com/optical-components/lenses/plano-concave-lenses/.
