33-014 15mm Dia. UVFS Laser Line Aspheric Lens; EFL=15mm; NA=0.5 V-Coat 532nm

This is the 33-014 model from Edmund Optics, a 15mm Dia. UVFS Laser Line Aspheric Lens, specifically designed for use with a 532nm wavelength. The lens boasts an EFL (Effective Focal Length) of 15mm and a numerical aperture (NA) of 0.5, making it a versatile choice for various optical applications.

The lens is made from syn hpfs7980 corning, a material known for its optical properties. It features a V-Coat 532nm coating on both the front and back surfaces, enhancing its performance in specific wavelength ranges. The coating helps reduce reflection and increase transmission, which is particularly beneficial when dealing with laser light.

The lens's geometry is another notable feature. It has an inner radius of 0 and an outer radius of 0, with a diameter of 15mm. The edge thickness is 2.43mm, and the center thickness is 7.3mm. The front and back surfaces have different curvatures, with r1 being 6.877 and r2 being 0. This asymmetry contributes to the lens's ability to focus light accurately.

The lens's aspheric design is a significant advantage. Unlike spherical lenses, aspheric lenses can focus light more accurately over a wider range of wavelengths and field angles. This makes them ideal for applications that require high-precision focusing, such as laser machining, medical imaging, and beam shaping.
