37-419 15mm Dia. N-SF6 Precision Aspheric Lens; EFL=11.25mm; NA=0.66 Uncoated

The 37-419 is a high-precision aspheric lens, 15mm in diameter, with a numerical aperture (NA) of 0.66, uncoated, and sourced from Edmund Optics. This lens is designed for use with a wavelength of 587.6nm, making it suitable for a wide range of optical applications.

The lens features a high-quality N-SF6 Schott material, ensuring excellent optical performance. The aspheric design of the lens helps to minimize spherical aberration, providing sharper images and improved light transmission compared to traditional spherical lenses.

The geometry of the lens includes an inner radius of 0mm, an outer radius of 0mm, a diameter of 15mm, and a thickness at the edge of 6.67mm. The effective focal length (EFL) is 11.25mm, and the back focal length (BFL) is 5.71mm. The lens has a thickness at the center of 10mm, with a k1 value of -0.8308645 and a k2 value of 0.

The lens's NA of 0.66 indicates a wide acceptance angle, making it suitable for high-resolution imaging applications. The uncoated design of the lens provides a cost-effective solution, although it may result in lower light transmission and higher susceptibility to environmental factors compared to coated lenses.

The lens is currently in stock and available for purchase through the Edmund Optics website, as indicated by the "weblink status" field in the item data.
