37-416 12.5mm Dia. N-SF6 Precision Aspheric Lens; EFL=9.5mm; NA=0.66 Uncoated

This is the 37-416 model from Edmund Optics, a high-precision aspheric lens with a 12.5mm diameter and a numerical aperture of 0.66. The lens is made from N-SF6 Schott, a high-refractive index glass that is often used in optical systems requiring high performance.

The lens has an effective focal length of 9.5mm, making it suitable for applications that require a compact optical system. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality.

The lens is uncoated, meaning it does not have any anti-reflective coatings. While this may result in higher reflective losses, it can also make the lens more cost-effective and suitable for applications where such coatings are not necessary.

The lens has a thickness of 4.96mm at the edge and 7.7mm at the center. The front surface of the lens has a radius of curvature of 7.649mm, with higher-order aspheric terms (k1) of -1.280869.

This lens is available for purchase through the Edmund Optics website, and as of the last update, it is in stock. For more detailed specifications and purchasing information, please refer to the provided weblink.
