48-055 12mm Dia. x -30mm FL; Uncoated; UV DCV Lens
The 48-055 is a spherical lens with a base shape of circle, sourced from the reputable vendor, Edmund Optics. This lens falls under the category of concave-concave lenses, making it suitable for specific optical applications. The lens has a diameter of 12mm and a thickness of 3.18mm at the edge, while the center thickness measures 2mm. The effective focal length (EFL) of this lens is -30mm, indicating its diverging nature.
The lens's first radius of curvature (R1) is -27.81mm, and the second radius of curvature (R2) is 27.81mm, which contributes to its concave-concave structure. The back focal length (BFL) of this lens is -30.68mm. The lens does not have any inner or outer radius, indicating it is a simple lens without any additional features.
This lens is made of fused sil mal-1965, a material known for its optical properties. The lens is designed to work at a wavelength of 587.6nm. The lens does not have any coating, which means it is uncoated. This could lead to higher reflections and lower transmission, but it also means the lens is less prone to contamination and damage due to coating layers.
