The KGA440-B Geltech Molded Glass Aspheric Lens is a very economic choice for collimating or focusing light at high magnification. It is made from Corning C0550 glass, which features low dispersion (Vd=50.40). Typical applications include fiber coupling, laser diodes, medical lasers, optical data storage, and barcode scanners. This 4.70 mm diameter lens has an effective focal length of 2.95 mm and a 0.53 NA. It has a NIR anti-reflective coating for 600-1050 nm.
