354105 7.2 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=5.5 mm; NA=0.6 Uncoated

The 354105 is a high-quality aspheric lens from Thorlabs, designed with a 7.2 mm diameter and a molded D-ZK3 CGDM material. This lens is specifically engineered for use with a wavelength of 633 nm, making it suitable for a wide range of optical applications.

The lens features an effective focal length (EFL) of 5.5 mm, which is a crucial specification for determining the lens's magnification power. The EFL is the distance from the lens's center to the point at which light rays converge or diverge. In this case, the EFL indicates that the lens has a moderate magnification power, which is ideal for many optical systems.

The lens's numerical aperture (NA) is 0.6, a measure of the lens's ability to gather and focus light. A higher NA allows for a wider angle of acceptance and a greater resolution, making this lens suitable for high-resolution applications.

The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. While coatings can reduce reflection and increase transmission, an uncoated lens can be advantageous in certain applications where minimal interference is required.
