The KGA671-A-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-LaK6 glass, which features low dispersion (Vd=52.65). Typical applications include fiber coupling, laser diodes, medical lasers, optical data storage, and barcode scanners. This 6.325 mm diameter lens has an effective focal length of 4.00 mm and a 0.60 NA. It has a Visible anti-reflective coating for 350-700 nm and is mounted in a durable stainless steel housing with a threaded exterior.
