22-709 100mm Dia. N-SF5 Precision Aspheric Lens; EFL=80mm; NA=0.63 BBAR 425-675nm
The 22-709 is a high-performance aspheric lens, boasting a 100mm diameter and a numerical aperture (NA) of 0.63. This lens is designed using N-SF5 Schott glass, a material known for its excellent optical properties, making it suitable for a wide range of applications.
The lens is visibly coated with BBAR (Broadband Anti-Reflection) coating, which enhances its performance in the 425-675nm wavelength range. This coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. The BBAR coating also minimizes dispersion, resulting in clearer and sharper images.
The lens geometry is meticulously designed, with an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 5.78mm. The effective focal length (EFL) is 80mm, and the back focal length (BFL) is 61.35mm. The lens features a high refractive power, thanks to its aspheric shape, which is defined by a conic constant of -0.786 and a quadratic term of 0.
The lens has a center thickness of 31.2mm, and its front surface has a radius of curvature of 53.817mm. The lens is designed to minimize spherical aberration, coma, and other optical aberrations, ensuring high-quality imaging.
