354220-1064 7.2 mm Dia. D-ZK3 Molded Glass Aspheric Lenses; EFL=11 mm; NA=0.25 1064nm V-Coat

The 354220-1064 is a high-quality aspheric lens, precision-molded from D-ZK3 glass, a type of glass known for its excellent optical properties. This lens boasts a diameter of 7.2 mm and a thickness of 4.212 mm at the edge, making it a compact yet robust optical component. The effective focal length (EFL) of this lens is 11 mm, which is a versatile focal length for many optical applications.

The lens features a high numerical aperture (NA) of 0.25 at 1064 nm, which allows for a wide field of view and high light-gathering capability. The aspheric design of the lens helps to correct spherical aberration, a common issue in traditional spherical lenses, resulting in improved image quality and resolution.

The lens is coated with Thorlabs' V-AR-1064 coating on both the front and back surfaces. This anti-reflection coating is specifically designed for use at 1064 nm, reducing surface reflections and increasing transmission, thereby enhancing the overall performance of the lens.
