The 48-295 is a 25mm diameter, 60mm focal length, uncoated, UV double-convex lens sourced from Edmund Optics. This lens is a spherical lens with a convex-convex base shape and a circular geometry, designed for use in the ultraviolet spectrum at a wavelength of 587.6nm.
The lens has a diameter of 25mm, with a thickness of 2.59mm at the edge and 5.52mm at the center. The effective focal length (EFL) is 60mm, and the radii of curvature are 54.14mm for the first surface and -54.14mm for the second surface. The back focal length (BFL) is 58.08mm. The lens does not have any coating, as indicated by the "uncoated" label in its name.
The lens is made of fused silica, as indicated by the material ID "fused sil mal-1965". This material is known for its high transparency in the UV range, making it suitable for UV applications. The lens is designed to be used in a spherical configuration.
The item data provides a comprehensive overview of the lens's specifications, making it easier for users to determine if this lens meets their specific needs. The lens's uncoated design, UV wavelength compatibility, and double-convex geometry make it a unique and valuable addition to any optical system.
