The KGA280-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 6.50 mm diameter lens has an effective focal length of 18.40 mm and a 0.15 NA. It has a NIR anti-reflective coating for 600-1050 nm.
