FocalRing®

The FocalRing® is a tool designed to reduce scanning failures and rescans commonly associated with poor focal plane definition of small tissue biopsies and cytology samples. The FocalRing comes embedded in a block and is meant to be sectioned at the same thickness as the tissue or cell structure it will be associated with. Once the ring is on the slide and deparaffinized, the desired sample (produced at the same thickness) is placed within the ring. The slide then goes through the standard processes to stain and digitize, with the FocalRing providing the plane of focus for whole slide scanning.
