37-428 25mm Dia. N-SF6 Precision Aspheric Lens; EFL=25mm; NA=0.5 Uncoated
This is the 37-428 model from Edmund Optics, a 25mm Dia. N-SF6 Precision Aspheric Lens with an effective focal length (EFL) of 25mm and a numerical aperture (NA) of 0.5, uncoated. The lens is made of N-SF6 Schott, a high-quality optical material known for its excellent transmission properties in the visible spectrum.
The lens features a base shape of a circle, with an inner radius of 0 and an outer radius of 0. The diameter of the lens is 25mm, and it has a thickness of 5.86mm at the edge and 9.86mm at the center. The back focal length (BFL) of the lens is 19.54mm.
The lens's aspheric shape is defined by its first and second radii of curvature, r1 and r2, which are 20.13mm and 0mm, respectively. The lens's shape is further defined by its conic constant, k1, which is -0.8641265. The lens does not have any coating, as indicated by the empty 'coating' parameter in the item data.
The lens is designed to operate at a wavelength of 587.6nm. It is in stock and available for purchase, as indicated by its weblink status. For more information, users can visit the provided weblink.
