354061-B 6.325 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=11 mm; NA=0.24 AR 600-1050nm

The 354061-B is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a type of glass known for its excellent optical properties. This lens boasts a diameter of 6.325 mm and a thickness of 1.754 mm at the edge, making it a compact yet robust optical component. The lens's effective focal length (EFL) is 11 mm, which is a versatile length suitable for a wide range of optical applications.

The lens's aspheric design, characterized by its non-spherical surface, offers superior optical performance over traditional spherical lenses. This design helps minimize spherical aberration, a common issue in optical systems, thereby providing sharper images and improved light transmission. The lens's shape is further defined by its radii of curvature (r1 and r2), thickness at the center (2.434 mm), and conic constant (k1), all of which contribute to its unique optical properties.

The 354061-B lens features a numerical aperture (NA) of 0.24, which quantifies its ability to gather and focus light. A higher NA allows for a wider angle of acceptance and improved resolution, making this lens ideal for applications requiring high light-gathering capabilities.

The lens is coated with a broadband anti-reflective coating, specifically designed for the 600-1050 nm wavelength range. This coating reduces surface reflections, thereby enhancing light transmission and improving overall system performance.
