354105-B 7.2 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=5.5 mm; NA=0.6 AR 600-1050nm

The 354105-B is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a type of CGDM material, and features a 7.2 mm diameter. This lens is designed for use with a wavelength of 633 nm and boasts an effective focal length (EFL) of 5.5 mm, making it suitable for a wide range of optical applications.

The lens's geometry includes an inner radius of 0 and an outer radius of 0, with a thickness at the edge of 1.286 mm. The center thickness is 2.937 mm, providing excellent optical performance and durability. The lens's shape is defined by its front and back radii (r1 and r2), which are 0 and -3.214021, respectively. The lens's numerical aperture (NA) is 0.6, indicating a wide acceptance angle and high light-gathering capability.

The 354105-B lens is coated with a broadband anti-reflective coating, suitable for wavelengths from 600 to 1050 nm, on both the front and back surfaces. This coating reduces surface reflections, enhancing the lens's transmission and overall optical performance.

This lens is available from Thorlabs and is currently in stock, making it an ideal choice for users seeking a reliable and high-performing optical component.
