The KGA220-B-MT Geltech Molded Glass Aspheric Lens is a very economic choice for collimating or focusing light at high magnification. It is made from CDGM D-ZK3 glass, which features low dispersion (Vd=60.71). Typical applications include fiber coupling, laser diodes, medical lasers, optical data storage, and barcode scanners. This 7.20 mm diameter lens has an effective focal length of 11.0 mm and a 0.25 NA. It has a NIR anti-reflective coating for 600-1050 nm and is mounted in a durable stainless steel housing with a threaded exterior.
