    Gradient-index relay lenses

    April 1, 1996
    The EndoGRINS gradient-index relay lenses are designed for use in boroscopes and ridged endoscopes. The lenses serve as replacements for fiberoptic image-conduit designs and in fiber coupling and collimating applications. One lens can eliminate many conventional optical elements and the associated placement and alignment tasks. Features include diameters from 0.98 to 2.68 mm, axial resolution of 200 lp/mm, and wavefront quality of 1/8 wave.
