She states, "I've never smoked and I don't drink, but I am so afraid of this high blood pressure. Laser light generally differs from other light in being focused in a narrow beam, limited to a narrow range of wavelengths (often called "monochromatic"), and consisting of waves that are in phase with each other. narrow range of wavelengths), through a sample and onto a light meter. Gray. All photodetectors are preferentially sensitive to a particular narrow band of wavelengths in the range of 0.51.2 m and all have a form of output that varies in a highly nonlinear fashion with temperature, and thus a microcomputer inside the instrument is highly desirable.

Optical filtering was first done with liquid-filled, glass-walled cells; [citation needed] they are still used for special purposes. For constructive interference, the difference in wavelengths will be an integer number of whole wavelengths. The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy. The SWIR spectral range is characterized by many narrow and strong absorption lines of atmospheric gases, mainly H 2 O, CO 2, O 2, and CH 4 (see, e.g., Figures 1C, 7). The visible light spectrum is the segment of the electromagnetic spectrum that the human eye can view. Where A is absorbance, is molar absorptivity, b is the path length of the cell and C is the concentration of the solution.
