Pharmaceutical PSA Pattern Graticle G-57, 21 mm, Glass sandwich, Each

Details

This graticule was designed for the pharmaceutical industry. However, it is also useful where particle size considerations are restricted to 10 mm and 25 mm. Dots and circles give quick references for these two sizes. In addition a scale is incorporated. The microscope must be calibrated when ordering this graticule, such that the circle must equate to 1 mm on the microscope stage.
