354105-A 7.2 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=5.5 mm; NA=0.6 AR 350-700nm

The 354105-A is a high-quality aspheric lens from Thorlabs, designed with a 7.2 mm diameter and a molded D-ZK3 glass construction. This lens is specifically engineered for use with a wavelength of 633 nm, offering a superior level of performance and precision.

The lens features an effective focal length (EFL) of 5.5 mm, providing a compact and efficient optical solution. The aspheric design of the lens helps to minimize spherical aberration, delivering a higher level of optical accuracy compared to traditional spherical lenses.

The lens has a numerical aperture (NA) of 0.6, which allows for a wide angle of acceptance and a high level of light gathering capability. This makes the lens ideal for use in a variety of applications where high light collection efficiency and wide angles are required.

The lens is coated with an anti-reflective (AR) coating, which is designed to reduce surface reflections and increase transmission over the 350-700 nm spectral range. This coating helps to improve the overall performance and efficiency of the lens, making it suitable for use in a wide range of optical systems.
