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.
Mix mesh sizes and grid types and still qualify for quantity discounts.
