A230-A 6.33 mm Dia. S-NPH1 Molded Glass Aspheric Lenses; EFL=4.51 mm; NA=0.55 AR 350-700nm
The A230-A is a high-quality aspheric lens from Thorlabs, designed with a 6.33 mm diameter and a molded S-NPH1 Ohara glass material. This lens is specifically engineered for use with a wavelength of 780 nm, offering a superior optical performance. The lens features an effective focal length (EFL) of 4.51 mm, providing a compact and efficient solution for various optical applications.
The A230-A lens boasts a high numerical aperture (NA) of 0.55, enabling excellent light-gathering capabilities and a wide field of view. The lens is coated with an anti-reflective (AR) coating, optimized for the 350-700 nm wavelength range, which significantly reduces surface reflections and improves overall transmission.
The lens geometry includes a center thickness of 2.94 mm and an edge thickness of 1.36 mm, contributing to its robust design and high optical performance. The aspheric shape of the lens (k1 = 0, k2 = -0.1263039) ensures minimal spherical aberration, providing superior image quality and accuracy.
