15-012 150 mm Dia. N-SF5 Precision Aspheric Lens; EFL=120mm; NA=0.63 Uncoated
The 15-012 is a high-precision aspheric lens offered by Edmund Optics, featuring a 150 mm diameter and a numerical aperture (NA) of 0.63. This lens is designed for use with a wavelength of 587.6 nm and is made from N-SF5 Schott glass, a material known for its excellent optical properties.
The lens's geometry is optimized for superior performance. It has an effective focal length (EFL) of 120 mm, a base shape of circular, and an inner radius of 0 mm. The outer radius is also 0 mm, and the lens has a thickness of 7.3 mm at the edge. The center thickness is 45.4 mm, and the lens's conic constant (k1) is -0.843.
The aspheric design of the lens helps to reduce spherical aberration, providing a higher quality image than spherical lenses. The lens has a high NA, which allows for a larger amount of light to be collected, making it ideal for use in high-resolution imaging applications.
The lens is uncoated, which means it does not have any anti-reflective coatings. While this can lead to some light loss due to reflection, it also means that the lens is less susceptible to damage from environmental factors.
The lens is currently in stock and available for purchase from the Edmund Optics website. It is a versatile and high-performance optical component that would be a valuable addition to any optical system.
