37-438 50mm Dia. N-SF6 Precision Aspheric Lens; EFL=30mm; NA=0.83 Uncoated

This is the 37-438 model from Edmund Optics, a high-precision aspheric lens with a 50mm diameter and a numerical aperture of 0.83. The lens is made from N-SF6 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 spherical lenses, resulting in improved image quality and resolution.

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 7.35mm, and the thickness at the center is 21.56mm. The lens has a high numerical aperture (NA) of 0.83, which allows for a larger amount of light to be collected, making it ideal for use in bright environments or for applications that require high light gathering capabilities.

The lens is uncoated, which means that it does not have any anti-reflective coatings. While this may result in a higher level of light reflection, it also means that the lens is more durable and resistant to scratches and other forms of damage.

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.
