112-0205E 25.4 mm Dia. x -30 mm FL; Uncoated; Plano-Concave Lens
The 112-0205E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens is characterized by its circular base shape and uncoated surface, making it a versatile option for various optical applications.
The lens has a diameter of 25.4 mm and a thickness at the edge of 7.9 mm. The center thickness is significantly less at 1.4 mm, demonstrating the concave nature of the lens. The effective focal length (EFL) is -30 mm, indicating that it diverges light passing through it. This property is further emphasized by its radius of curvature (R1) of -15.6 mm.
The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number. The lens is designed to work at a wavelength of 546 nm. The inner and outer radii are both zero, indicating that the lens is a simple plano-concave design.
This lens is in stock and available for immediate purchase. For more information, please refer to the vendor's website at http://eksmaoptics.com/optical-components/lenses/plano-concave-lenses/.
