Integral light transmission

To address protection, use of tests (see Attachment A) for light transmission, moisture permeation, microbial limits, and sterility are generally considered sufficient. Testing for properties other than those described above (e.g., gas transmission, solvent leakage container integrity) may also be necessary. 

Light Transmission. This was determined on a GE recording spectrophotometer using thin films, followed by integration of the transmission over the visible range. 

Fig. 26. Integrated SAXS intensity (arbitrary units) vs polymerization time at 50 °C for an epoxy-diamine system (DGEBA-3DCM) modified by 15 wt% of two different rubbers (ETBN and NFBN). Morphology of the particles (p-phase), as observed by transmission electron microscopy (TEM), is plotted qualitatively. Cloud-point times (tcp), determined by light transmission, and gelation times are indicated...

One form of the in-hne array benefits from the relatively large aperture and light transmission efficiency of Schmidt reflective optics by combining the electron optics and phosphor screen with the projection optics in a single tube. The principle components of an integral Schmidt system are shown in Fig. 5.121. 

Let us consider investigation of stresses in a 3-D specimen. It has been shown [1] that in the case of weak birefringence a 3-D specimen can be investigated in a conventional transmission polariscope as if it were a two dimensional specimen. On every ray of light it is possible to determine the parameter of the isoclinic and the optical path difference A. The latter are related to the components of the stress tensor on the ray by linear integral relationships... 

When light is directed onto a sample it may either be transmitted or reflected. Hence, one can obtain the spectra by either transmission or reflection. Since some of the light is absorbed and the remainder is reflected, study of the diffuse reflected light can be used to measure the amount absorbed. However, the low efficiency of this diffuse reflectance process makes it extremely difficult to measure 120) and it was speculated that infrared diffuse reflection measurements would be futile 120). Initially, an integrating sphere was used to capture all of the reflected light121) but more recently improved diffuse reflectance cells have been designed which allow the measurement of diffuse reflectance spectra using FT-IR instrumentation 122).
