The Finder range
of grids are useful in applications where specific areas of
mesh need to be uniquely identified. These areas range from
blocks of 1 to 9 grid cells, and can typically be relocated
using an alphabetical and/or numerical code built into the mesh.
G100F1 (new) Each of the 60 square
grids is identified using a base two binary numbering system.
The six binary number symbols appear on the bottom grid bars
along the horizontal axis. Zero is represented by a short
pillar and one by a longer pillar. Below is an enlarged view
of grid no.9 - a long pillar at the extreme right represent
decimal 1 and a long pillar fourth from the right represent
a decimal 8.
G200F1 An alpha-numerical
code identifies 48 blocks of 6 cells, delineated by thicker
grid bars. Each block's code is attached to the baseline of
its centre-bottom cell, letters representing rows and numbers
representing columns.
G200HF3
322 cells are uniquely identified by an alphanumeric code. At
light microscope level, this code can be referenced from the
letters and numbers on the rim of the grid, representing rows
and columns respectively. At the electron microscope level,
the row letter is indicated by a symbol to the bottom left of
the cell. The column number is indicated by a binary coding
attached to the baseline of the cell.
G200F4
A 15 by 15 grid of cells is indexed with letters representing
columns, and numbers representing rows. Each cell is asymmetrical
due to a marking at every grid bar intersection, similar to
the centre marking detailed on the Centre/Rim Mark Specs page,
allowing grid orientation to be determined at microscopic levels.
