Precision Mechanics: Dual coaxial coarse and fine focus controls with a minimum fine focus increment of 2 µm
The demonstrator can open down the center
and an eye hook
allowing the calculation of velocity based on the rate of hammering and the distance between dots
Model of Seeds Germination Precision Mechanics: Dual coaxial coarseSize: 585mm x 140mm x 350mm. Comparative composition to illustrate different modes of germination, namely rye (10x magnification), bean (5x magnification) and spruce (20x magnification). The model allows for a good illustration. Shows the formation of a green tip emerging from a grain of rye (Secale cereale) (monocotyledon), Shows the appearance of two cotyledons on the bean (Phaseolus vulgaris) (dicot). Shows the spruce seedling (Pica excels)
