37-436 40mm Dia. N-SF5 Precision Aspheric Lens; EFL=30mm; NA=0.66 Uncoated

This is the 37-436 model from Edmund Optics, a high-precision aspheric lens with a 40mm diameter and a numerical aperture of 0.66. The lens is made of N-SF5 Schott, a high-refractive index glass, and is uncoated.

The lens has an effective focal length (EFL) of 30mm, making it suitable for applications that require a wide field of view and high resolution. The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional lenses, which leads to improved image quality and contrast.

The lens has a base shape of circular, with an inner radius of 0 and an outer radius of 0. The thickness at the edge is 8.83mm, and the thickness at the center is 20mm. The lens's front surface has a radius of curvature of 20.182mm, and the back surface is flat.

The lens's high numerical aperture (NA) of 0.66 allows for a high light-gathering capability, making it ideal for use in bright-field microscopy, laser beam shaping, and other high-resolution imaging applications.

The lens is currently in stock and can be purchased directly from the Edmund Optics website. The link to the product page is provided in the item data for your convenience.
