Welcome to our FAQ blog post about the Lumea FocalRing. We compiled a list of frequently asked questions about this technology so you can learn how it benefits pathology labs. 

What is the 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. 

How does it work?

FocalRing on a slideThe FocalRing comes embedded in a block. When ready to use it, section it the same thickness as the tissue or cell structure it will be associated with. Once a section of the ring is on the slide and deparaffinized and cleared, 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.

What specimen types work with the FocalRing?

The FocalRing is made for small biopsy and low-cellularity cytology slide preparation.

What is the purpose of the FocalRing?

The purpose of the FocalRing is to reduce the amount of rescans common with small tissue biopsies and low-cellularity cytology.

How many uses can I get out of one FocalRing?

You can expect about 300 slides out of one FocalRing block if cut on the microtome at 4 microns thick.
