Microscopy from Scientific Research

Diamond and square motifs produced by stacking identical line patternsd=31μm$d = 31\; \umu \text{m}$of silver chromate. Irradiating these microscopic patterns with a green laser (λ = 532 nm) produces a diffraction pattern that is in good agreement with the microscopic spacing (d=mλ2sin(θ)$d= \frac{m\lambda }{2sin(\theta )}$, diffraction:d=32μm$d = 32 \; \umu \text{m}$, directly observed:d=31μm$d = 31 \; \umu \text{m}$).
