354340-A 6.325 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=4 mm; NA=0.64 AR 350-700nm

The 354340-A 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 1.484 mm at the edge, making it a compact yet robust optical component. The lens has an effective focal length (EFL) of 4 mm, which is a crucial parameter in determining the lens's magnification and field of view.

The lens's aspheric design is a significant feature, enabling it to correct spherical aberration, a common issue in traditional spherical lenses. This design ensures superior image quality, making the 354340-A an ideal choice for applications requiring high-resolution imaging.

The lens's numerical aperture (NA) is 0.64, indicating a wide acceptance angle and high light-gathering capability. This feature is particularly beneficial in applications where high light throughput and a large field of view are required.

The lens is coated with a broadband anti-reflective coating, optimized for the 350-700 nm wavelength range. This coating reduces surface reflections, enhancing the lens's transmission and improving overall system performance.

The 354340-A is available from Thorlabs and is currently in stock, ensuring quick delivery for your optical needs. For more information, please refer to the vendor's website.
