33-017 15mm Dia. UVFS Laser Line Aspheric Lens; EFL=12.5mm; NA=0.6 V-Coat 1064nm

This is the 33-017 model from Edmund Optics, a 15mm diameter UVFS Laser Line Aspheric Lens, specifically designed for use with a wavelength of 1064nm. The lens boasts an EFL (Effective Focal Length) of 12.5mm and a high numerical aperture (NA) of 0.6, making it ideal for applications that require high resolution and light-gathering capabilities.

The lens is made from syn hpfs7980 corning, a material known for its excellent optical properties. It features a V-coat 1064 coating on both the front and back surfaces, enhancing its performance in laser applications by reducing reflections and improving transmission.

The lens geometry is intricately designed with a range of parameters. The inner radius is 0, while the outer radius is also 0. The thickness at the edge is 2.47mm, and the EFL is 12.5mm. The aspheric design is defined by the radii r1 and r2, which are 6.877mm and 0, respectively. The back focal length (BFL) is 6.33mm, and the thickness at the center is 9mm.

The aspheric shape of the lens is precisely defined by the coefficients k1, k2, and so on. In this case, k1 is -1.123452, with the other coefficients being 0. This design allows for superior optical performance compared to traditional spherical lenses, minimizing spherical aberration and distortion.
