GEM Lenses
Generic Emission Microscope (GEM) lenses are utilized in an advanced class of microscopes that look for near-infrared thermal signals given off from faulty integrated circuits. GEM lenses are designed to look for these faulty circuits by providing a macro field of view of the sample (at magnifications ranging from 0.8X to 1.0X).   

The lenses are designed over a near-infrared spectrum ranging from 750 to 1150nm. They are of exceptional high numerical aperture (1X/0.40NA and 0.8X/0.32NA).

The benefit of such lenses is they offer rapid full field inspection of a large field-of-view. After identification has been established, high magnifying objectives can be used to examine details of the circuit.
