SPI Regular Grids - Micron Type

Grids with center mark

• Featuring asymmetric center mark for relocating and orienting grid squares when examining specimens.
• Order numbers include a code letter that indicates materials of contruction:
C=Copper

N=Nickel

Mesh sizes followed by "TT" indicate thin/thick bar matrix.
Mesh sizes followed by "H" indicate tab handle.
Available in square & non-square mesh styles, in both copper and nickel.
Grids are 3.05 mm diameter unless otherwise noted. Some patterns available 2.3 mm diameter as well.
Grids vary in thickness from 7 mils (178 µm) to 5 mils (12.7 µm) depending on mesh size, the highest mesh size having the thinnest grids. Thinner grids are an advantage when doing tilting experiments.
