Optical table half grid adapters

Optical tables normally use a grid distance of 25mm.If you mount an additional optical breadboard onto the table, its possible that its grid is shifted exactly by half.This adapter helps to position optical components in half positions in between grid positions (either center in just one direction or two directions), in a more reliable and easy way than using clamping forks.Depending on required flexibility and the size of your optical component, there are two different sizes available.Screw your optical component from the back onto the adapter using an M6 screw and then screw the adapter onto the table.
