Figure 2. Interference contrast micrograph of a frontal section of the compound eye that shows the retina and lamina compartments separated by a basement membrane (BM). Lateral facet lenses are present on the outer edge of the section. Each lens in the eye images light onto a single ommatidium. Peripheral photoreceptors in each diamond-shaped ommatidium project axons across the basement membrane with 1 1 retinotopy onto the lamina cartridges.

Figure 3. Interference contrast micrograph of a 1-fim-thick section of the lamina that shows photoreceptor axon terminals surrounding the paired mono-polar neurons in each cartridge.

Figure 13. a. Interference-contrast optical micrograph of marked bits on the infrared DIP disk as a function of laser pulse energy, b. Scanning electron micrograph of marked bits on the infrared DIP disk. 

Figures 13a and 13b show the optical interference-contrast and SEM micrographs, respectively, of the marked bits at various energy levels. The high spatial resolution of the Infrared disk Disc is apparent from the uniform, submicron dimensions of the marks.

Figure 7.22 Microstructure of acidified mixed emulsions (20 vol% oil, 0.5 wt% sodium caseinate) containing different concentrations of dextran sulfate (DS). Samples were prepared at pH = 6 in 20 mM imidazole buffer and acidified to pH = 2 by addition of HCl. Emulsions were diluted 1 10 in 20 mM imidazole buffer before visualization by differential interference contrast microscopy (A) no added DS (B) 0.1 wt% DS (C) 0.5 wt% DS (D) 1 wt% DS. Particle-size distributions of the diluted emulsions determined by light-scattering (Mastersizer) are superimposed on the micrographs, with horizontal axial labels indicating the particle diameter (in pm).

Fig. 16 Series of interference contrast optical micrographs of an initially 4.2 wt % solution of n-Ci98H398 in phenyldecane at successive times (indicated) upon reaching Tc = 97.4 °C. The progress of the dilution wave is shown in (b) through (f), triggering the processes of crystallization of needle-like extended-chain crystals and simultaneous dissolution of folded-chain crystals. The needles form along the two 100 faces of the truncated lozenge shaped folded-chain crystals, with a third parallel crystal often appearing in the middle. Bar = 20 pm.

The vesicles were grown at 2.5 V and 10 Hz for 2-4 h light micrographs were taken in the differential interference contrast (DIC) mode (A) domes, (B) mushrooms, (C) spheres, and (D) cut-spheres. Bar corresponds to 100 pm. (Figures B and C reproduced ft-om Langmuir, 14, 2712 (1998) by permission of the American Chemical Society).
