Transmitted light microscop

Polished pellets and thin sections were made of each incremental fraction across the xenolith for reflected and transmitted light microscopic examination. Thin sections revealed little because of the opacity of the coke. However, the pellets, which were made by mounting the coke in plastic, were invaluable to the study. 

Macroscopic Observations of Three Phase Foam Structure. In Figures 2 and 3 are shown foam drainage results in the presence of Salem crude oil with the surfactants C. OS and C..AOS at 1 wt% NaCl. obtained from the transmitted light microscope. Surfactant chain length is clearly seen to be a significant factor (compare Figure 2 with Figure 3). 

Figure 5. The process of image formation by the objective in a transmitted light microscope when light is normally incident on the specimen. A diffraction pattern of the specimen arises at the objective back focal plane, as illustrated by ray paths drawn as thin lines. The "zero order , consisting of undiffracted rays, has been identified by shading. A finer structure in the specimen leads to a greater divergence of diffracted orders, eventually placing them beyond the aperture of the objective. Principal ray paths drawn as thick lines illustrate the formation of detail in the image.

A light microscope for examining material microstructure can use either transmitted or reflected light for illumination. Reflected light microscopes are the most commonly used for metallography, while transmitted light microscopes are typically used to examine transparent... 

Initially the octyl to dodecyl compounds were prepared and these were found to exhibit relatively normal behavior, i.e. smectic A phases were found for the lower homologues with smectic and ferroelectric smectic C phases occurring for the higher members. However, when the tetradecyl homologue was examined in the polarizing transmitted light microscope, an iridescent helical mesophase was observed which upon cooling underwent a further phase transition to a ferroelectric smectic phase. In addition, this compound was also found to exhibit antiferroelectric and ferrielectric phases.

An Olympus BHA transmitted light microscope with its polarizer and analyzer set at extinction, and long working distance objectives was used to observe the different stress patterns resulting from interphase changes. 

The cross-section of the above specimens was further investigated to determine the changes in the fiber morphology as well as the fabric properties. In the cross-sectional study, both warp and weft yams of the specimens were carefully removed from the fabric, and then investigated by a traditional optical microscopy and a SEM. In the optical microscope, the sample was prepared by procedures described in standard AATCC20 a bundle of yams were used to pack the hole of a stainless steel plate, then a sharp razor blade was used to produce a smooth cut on both sides of the plate (AATCC, 2004). The steel plate was then examined by a transmitted light microscope with magnification of 500 x. 

Microscopic analysis.Optical microscopy measurements were performed in inert medium (isopropyl alcohol) and swelling medium (isotonic saline) by means of a transmitted light microscope (Microstar 120, Reichert-Young Amer. OPT., USA-Buffalo, N.Y.), fitted with a Polaroid camera (3.5 x 4.5) and with standard ocular micrometer.

Slides with immunoperoxidase reaction can be observed with any type of transmitted light microscope. After IMF reactions, slides can be viewed with any type of fluorescence microscope or with a confocal microscope. See Notes 1-3.
