354330-B 6.325 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=3.1 mm; NA=0.7 AR 600-1050nm
The 354330-B is a high-quality aspheric lens from Thorlabs, designed with a 6.325 mm diameter and a center thickness of 3.214 mm. This lens is made from D-ZK3 glass, a molded glass material known for its excellent optical properties. The lens features an effective focal length (EFL) of 3.1 mm and a numerical aperture (NA) of 0.7, making it suitable for a wide range of optical applications.
The lens's aspheric design helps to reduce spherical aberration, a common issue in optical systems, resulting in improved image quality and resolution. The geometry of the lens includes a range of parameters, such as inner and outer radii, thickness edge, and various coefficients (k1, k2, a2, a4, a6, a8, a10, a12, a14, a16) that define its precise shape and optical performance.
The lens is coated with a broadband anti-reflective coating, suitable for wavelengths between 600 and 1050 nm. This coating helps to minimize light loss due to reflection, enhancing the overall efficiency of the optical system. The coating is applied to both the front and back surfaces of the lens.
