354240-C 9.936 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=8 mm; NA=0.5 AR 1050-1700nm

The 354240-C is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a material renowned for its excellent optical properties. This lens boasts a diameter of 9.936 mm and a thickness of 1.438 mm at the edge, making it a compact yet robust optical component. The lens's effective focal length (EFL) is 8 mm, providing a concentrated, well-defined optical path.

The lens's design includes a front radius (R1) of 0 mm and a rear radius (R2) of -4.638124 mm, contributing to its high numerical aperture (NA) of 0.5. This high NA enhances the lens's light-gathering capability, making it suitable for applications requiring high light intensity or resolution.

The 354240-C is coated with a broadband anti-reflection (AR) coating, optimized for the 1050-1700nm wavelength range. This coating reduces surface reflections, improving transmission and minimizing unwanted optical losses. The lens's shape is aspheric, which helps to correct spherical aberration and other optical aberrations, thereby delivering superior image quality.
