Molded Glass Aspheric Lenses

Aspheric surface reduces spherical aberration
Numerical apertures from 0.15 to 0.68
Unmounted, or mounted with durable stainless steel
Visible or NIR anti-reflective coatings
Fewer optical components than spherical lens systems

These Geltech^TM Molded Glass Aspheric Lenses are a very economic choice for collimating or focusing light at high magnification. They are made from Corning C0550 glass, which features low dispersion (V_d=50.40). Typical applications include fiber coupling, laser diodes, medical lasers, optical data storage, and barcode scanners. All are available unmounted, and for diameters 6.325 mm and larger, these lenses can be mounted in a durable stainless steel housing with a threaded exterior.
