Gradient Index Imaging Microlenses
-
Available in diameters from 0.25 to 1.0mm
-
Magnifications from 5 to 20X
-
High resolution performance,
-
200 line-pairs per mm
These gradient index microlenses are optimized for imaging applications. They form an image at one face of the lens of an object at a working distance of 5mm from the opposite face of the lens. This image may be viewed directly by a 100X microscope or transferred to the distal end of a coherent fiber bundle or gradient index relay lens. The lenses are supplied uncoated and no coatings are offered.
