22-722 150mm Dia. N-SF5 Precision Aspheric Lens; EFL=120mm; NA=0.63 BBAR 600-1050nm
The 22-722 is a high-precision aspheric lens offered by Edmund Optics, boasting a 150mm diameter and a numerical aperture (NA) of 0.63. This lens is designed for use in the near-infrared (NIR) spectrum, specifically at a wavelength of 587.6nm.
The lens is made from N-SF5 Schott, a high-refractive index glass that is known for its excellent optical properties. The aspheric design of the lens helps to minimize spherical aberration, providing superior image quality.
The lens features a focal length (EFL) of 120mm, making it suitable for a wide range of applications. The front and back surfaces of the lens are coated with BBAR 600-1050, a broadband anti-reflection coating that enhances transmission in the 600-1050nm range.
The lens has a thickness of 7.3mm at the edge and 45.4mm at the center. The inner and outer radii are 0mm, and the lens has a base shape of circular. The front and back focal lengths are 92.86mm and 0mm, respectively.
The lens's geometry is defined by several parameters, including k1 (-0.843), k2 (0), and several other higher-order coefficients that ensure the lens's aspheric shape. The lens's shape is designed to provide superior performance, making it an excellent choice for a wide range of optical applications.
