354240-A 9.936 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=8 mm; NA=0.5 AR 350-700nm

The 354240-A is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a unique type of glass known 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 solution for various optical applications.

The lens has an effective focal length (EFL) of 8 mm, which is the distance from the lens's center to the focal point where light rays converge. This EFL makes the lens suitable for applications requiring a moderate level of magnification or minification.

The lens's numerical aperture (NA) is 0.5, indicating its ability to gather and focus light. A higher NA allows for a wider angle of acceptance and a sharper image, making this lens ideal for applications requiring high resolution and contrast.

The lens features advanced anti-reflective (AR) coatings on both the front and back surfaces, designed to reduce surface reflections and increase transmission in the 350-700nm spectral range. This coating enhances the lens's performance in a wide range of applications, including imaging, illumination, and beam manipulation.

The lens's aspheric design corrects spherical aberration, a common optical issue that can degrade image quality. This design ensures that the lens delivers superior image quality, even at wide apertures.
