for Transmission Electron Microscopy
[ Micron Index ] [ Micron Asbestos Reference Index ]Graticules Ltd. in England introduced reference patterns to optical microscopy and carried the advantages to electron microscopy. Graticules was the first to make reference "finder" electron microscope grids which are part of their "Maxtaform" grid group.
Other reference grids have since been developed, and all such patterns have certain features of their own which scientists and engineers find useful. Relocating a particular grid square or area by a logical alphabetical or numeric (or both) arrangement can reduce the time spent for specimen analysis. Exact grid square definition may even be a requirement in forensic and asbestos analysis. Certainly there can be greatly increased confidence by the electron microscopist that "that" precise grid square can be found where a feature is of interest while moving about the other parts of the specimen on the grid.
Your need or wish can most likely be filled with one or more reference grid styles listed below.

Gilder Finder GridEach 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. The enlarged section shown is of grid square no. 9 - a long pillar at the extreme right represents decimal 1 and a long pillar fourth from the right represents decimal 8.Pitch= 250µ; Bar width vertical axis= 40µ; Hole width, vertical axis= 210µ.

These grids are found to be very useful both in immunogold techniques (Nickel grids)
or AHERA studies (Copper or Nickel). Clean and sharp lines. Index l is 75 mesh for
the strong bars and each square is bisected in both directions with thinner bars.
INDEX l Locater GridEach square divided into triangles with bisectors and has an alphanumeric designation. 100 mesh.
