A230-C 6.34 mm Dia. S-NPH1 Molded Glass Aspheric Lenses; EFL=4.51 mm; NA=0.55 AR 1050-1620nm

The A230-C is a high-quality aspheric lens, precision-molded from S-NPH1 glass, a material renowned for its excellent optical properties. This lens boasts a diameter of 6.34 mm and an effective focal length of 4.51 mm, making it suitable for a wide range of applications. The lens features a high numerical aperture (NA) of 0.55, which allows for a larger light-gathering capacity and improved resolution.

The lens is coated with a broadband anti-reflection (AR) coating, specifically designed for the 1050-1620nm wavelength range. This coating significantly reduces surface reflections, thereby enhancing transmission and improving overall system performance. The lens is available from Thorlabs, a leading vendor in the optical components industry, and is currently in stock, ensuring quick delivery times.

The A230-C's aspheric design offers superior optical performance over traditional spherical lenses, correcting for spherical aberration and delivering sharper images. The lens's geometry includes a range of parameters, such as inner and outer radii, thickness at the edge and center, and conic constants, all of which contribute to its exceptional performance.
