112-0109E 12.7 mm Dia. x -50mm FL; Uncoated; Plano-Concave Lens
The 112-0109E is a Plano-Concave Lens, a type of spherical lens, sourced from EKSMA Optics. This lens is designed with a circular base shape and features a diameter of 12.7 mm and a thickness that varies from 3.5 mm at the edge to 2.7 mm at the center. The lens has an effective focal length (EFL) of -50 mm, making it suitable for applications that require a negative focal length.
The lens's inner and outer radii are 0, and its first radius of curvature (R1) is -25.9 mm. The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. The wavelength for this lens is 546 nm.
This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, it is still a versatile option for various applications due to its high-quality material and precise specifications.
