66-314 40 mm Dia. L-BAL35 Precision Aspheric Lens; EFL=40mm; NA=0.5 Uncoated
The 66-314 is a high-precision aspheric lens offered by Edmund Optics. This lens, with a catalog number 66-314, is made from L-BAL35 material, a product of Ohara. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties.
The lens has a base shape of a circle and a diameter of 40 mm. The inner radius is 0 mm, and the outer radius is also 0 mm. The thickness at the edge of the lens is 6.39 mm, and the effective focal length (EFL) is 40 mm. The lens's shape is defined by its first and second radii, r1 and r2, which are 24.681 mm and 400 mm, respectively. The back focal length (BFL) is 30.68 mm.
The lens's thickness at the center is 15.5 mm. The lens's numerical aperture (NA) is 0.5. The lens's shape is defined by its conic constant, k1, which is -0.622238. The lens's front diameter, front edge thickness, front curvature, and front conic constant are 0 mm, 0 mm, -4.22e-10, and -1.49e-12, respectively.
The lens is available from the vendor's website, and the link provided is valid and indicates that the lens is in stock. This lens is suitable for applications that require high precision and a wide field of view.
