354171-C 4.7 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=6.2 mm; NA=0.3 AR 1050-1700nm
The 354171-C is a high-quality aspheric lens from Thorlabs, designed with a 4.7 mm diameter and a molded D-ZK3 glass construction. This lens is specifically engineered for use in the 1050-1700nm wavelength range, making it ideal for a variety of applications in the infrared spectrum.
The lens boasts an effective focal length (EFL) of 6.2 mm, which is a crucial specification for determining the lens's magnification and field of view. The EFL, combined with the lens's numerical aperture (NA) of 0.3, allows for a wide range of imaging possibilities.
The aspheric design of the lens helps to minimize spherical aberration, a common issue in traditional lenses that can lead to distorted images. This aspheric shape is defined by its radii (r1 and r2), thickness at the center and edge, and its conic constant (k1). The lens's front and back surfaces have been coated with a broadband anti-reflective coating, which enhances transmission and reduces surface reflections.
