48-932 6mm Dia. x -9mm FL; Uncoated; Double-Concave Lens
The 48-932 is a spherical lens with a base shape of a circle, sourced from the reputable vendor, Edmund Optics. This lens falls under the category of a Spherical Lens (Concave-Concave) and is uncoated.
The lens has a diameter of 6mm and a thickness at the edge of 1.79mm, while the thickness at the center is 1mm. The Effective Focal Length (EFL) is -9mm, indicating that it is a double-concave lens. The first radius of curvature (R1) is -9.47mm, and the second radius of curvature (R2) is 9.47mm. The Back Focal Length (BFL) is -9.32mm.
The lens is made of n-BK7 Schott material, a popular choice for its high refractive index and low dispersion. It is designed to operate at a wavelength of 587.6nm. The lens does not have any coating, which means it is in its raw state and users may need to apply their own coating based on their specific requirements.
This lens is ideal for applications that require a negative focal length and a high-quality optical material. It can be used in various fields, including but not limited to, imaging systems, beam shaping, and laser applications.
