48-301 25mm Dia. x 250mm FL; Uncoated; UV Double-Convex Lens
The 48-301 is a 25mm diameter, 250mm 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 geometry, designed for use in the ultraviolet spectrum at a wavelength of 587.6nm.
The lens has a diameter of 25mm, with a thickness at the edge of 2.53mm and a center thickness of 3.21mm. The effective focal length (EFL) is 250mm, and the first and second radii of curvature (R1 and R2) are 228.73mm and -228.73mm respectively. The back focal length (BFL) is 248.9mm. The lens does not have any coating applied to it.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent transparency in the UV range, making it suitable for applications such as UV spectroscopy, UV imaging, and other UV-based optical systems.
Please note that the lens is uncoated, which means it does not have any anti-reflective or other surface coatings. This may result in higher levels of reflection, especially at the edges of the lens, and could potentially affect the performance of the lens in high-intensity light applications.
