Weibel 2 Graticle NGW2, 21mm, Each

Details

Used when making a surface to volume ratio of a structure per mass unit. This graticule consists of a number of short lines with interruptions as long as the lines. Basically, the number of intersections falling over the short lines is counted and the number of endpoints falling on the end of the structure is determined. Reference: E.R.
