Because the absorption coefficient of tissue is considerably lower in the near infrared ( NIR ) region ( 700-900 nm ), light can penetrate more deeply, to depths of several centimeters.

For the case of isotropic absorption and emission, the emission coefficient ( ) and absorption coefficient ( ) defined in the radiative transfer section above, can be expressed in terms of the Einstein coefficients.
43.
Reverberation chambers are used in acoustics as well as in electrodynamics, such as for measurement microphone calibration, measurement of the sound power of a source, and measurement of the absorption coefficient of a material.
44.
Its half-life in solution at pH 5 is 47 to 85 days . Because of its very high absorption coefficient ( Koc ), dicofol is expected to adsorb to sediment when released into open waters.
45.
:The absorption coefficient of UV-A in flesh is about ~ 50 / cm, meaning after 5 cm, the intensity would have fallen off by a factor of e-5 * 50 = 3.
46.
The absorption coefficient of the material in the modulator can be manipulated by the Franz-Keldysh effect, the Quantum-confined Stark effect, excitonic absorption, changes of Fermi level, or changes of free carrier concentration.
47.
Experimental results suggest an in vivo detection sensitivity of 0.1-1 �M for organic dyes with a minimum detectable optical absorption coefficient of 0.1 1 cm-1, such as indocyanine green and Alexa fluochromes.
48.
The value of QE _ i ( \ lambda ) is obtained by linking it with the absorption coefficient \ alpha ( \ lambda ), i . e . the number of photons absorbed per unit of length by a material.
49.
He was awarded his Doctor of Philosophy ( Ph . D . ) in physics in 1924, the first year in which Caltech awarded this degree, for his thesis on " the absorption coefficient for slow electrons in gases ".
50.
In electron energy loss spectroscopy, Kramers Kronig analysis allows one to calculate the energy dependence of both real and imaginary parts of a specimen's light optical permittivity, together with other optical properties such as the absorption coefficient and reflectivity.
