354240-B 9.936 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=8 mm; NA=0.5 AR 600-1050nm

The 354240-B is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a type of CGDM material. 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 effective focal length (EFL) of this lens is 8 mm, and it has a numerical aperture (NA) of 0.5, providing a wide field of view and high light-gathering capability.

The lens's front and back surfaces are coated with a broadband anti-reflective coating, specifically designed for the 600-1050nm wavelength range. This coating significantly reduces surface reflections, enhancing the lens's transmission efficiency and overall performance in various applications.

The lens's aspheric design allows for superior optical performance compared to traditional spherical lenses. It effectively corrects spherical aberration, coma, and other optical aberrations, delivering sharp images with high resolution and contrast. This makes the 354240-B an ideal choice for applications that require high-performance imaging, such as machine vision, beam shaping, or laser applications.

The lens is available from Thorlabs, a leading vendor in the optical components industry. According to the vendor's information, the lens is currently in stock, ensuring quick delivery and availability for your optical system needs.
