* We can make this item in any desired diameter not listed as a special order item. Please be sure to specify the diameter needed. Be sure that you give us the right diameter because a special order reticle, once ordered, is non-cancelable and the reticle once received, is non-returnable.

Weibel Type 2 for Stereology:

Used when making a surface to volume ratio of a structure per mass unit. The reticle consists of a number of short lines with interruptions as long as the lines. Basically the number of intersections falling over the short lines are counted and the number of end points falling on the end of the structure are determined.
