Replace bulky microscope objectives Couple light into and out of optical fibre or collimate diode lasers Convenient kit contains a large range of numerical apertures from 0.6 to 0.65 .
These compact glass aspheric lenses provide a convenient, high-quality alternative to microscope objectives. Unlike conventional spherical lenses, aspheric lens can refract light at large angles without introducing any significant aberration. This allows a single asphere to perform the same function as a compound lens system.
