354140-A 2.4 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=1.5 mm; NA=0.58 AR 350-700nm

The 354140-A is a high-quality aspheric lens from Thorlabs, designed with a 2.4 mm diameter and a focal length of 1.5 mm. This lens is made from D-ZK3 glass, a molded glass material known for its excellent optical properties. The lens features a numerical aperture (NA) of 0.58, indicating a wide acceptance angle and high light-gathering capability.

The lens is coated with an anti-reflective (AR) coating, specifically designed for the wavelength range of 350-700nm. This coating reduces surface reflections, enhancing the transmission of light through the lens. The lens has a center thickness of 1.02mm and edge thickness of 0.475mm, providing robustness and durability.

The aspheric design of the lens helps to reduce spherical aberration, a common issue in traditional spherical lenses. This results in improved image quality and increased design flexibility. The lens is suitable for use in a variety of applications, including imaging systems, beam shaping, and laser applications.

The 354140-A lens is currently in stock and available for purchase through the Thorlabs website. With its superior optical performance and robust design, this lens is an excellent choice for users seeking high-quality optical components.
