49-238 6mm Dia. x 6mm FL; Uncoated; UV Double-Convex Lens
The 49-238 is a 6mm diameter x 6mm focal length uncoated UV double-convex lens, available from Edmund Optics. This lens is a spherical lens with a convex-convex base shape and a circular design, offering a versatile solution for various optical applications.
The lens features a diameter of 6mm and a thickness of 1.97mm at the edge, with a center thickness of 4.1mm. The effective focal length (EFL) is 6mm, and the radii of curvature are 4.76mm for the first surface and -4.76mm for the second surface. The back focal length (BFL) measures 4.38mm.
The 49-238 lens is made of fused silica (mal-1965) material, ensuring high transmittance and durability. It is designed to work with a wavelength of 587.6nm. The lens does not have any coating, which may affect its performance in specific applications. However, its uncoated nature makes it suitable for use in environments where coated lenses might be damaged or contaminated.
