absorption cell

A simple section of waveguide can serve as an absorption cell.

"The absorption cells won't work."

Absolute stabilization of the laser's frequency (or wavelength) as fine as 2.5 parts in 10 can be obtained through use of an iodine absorption cell.

Multipass or long path absorption cells are commonly used to measure low-concentration components or to observe weak spectra in gases or liquids.

An important variation of the technique in which an alternating current is applied across electrodes within the absorption cell results in a modulation of the frequencies of rotational transitions.

A microwave spectrometer can be most simply constructed using a source of microwave radiation, an absorption cell into which sample gas can be introduced and a detector such as a superheterodyne receiver.

The blue CCD captures stellar activities while the red CCD falls into a temperature controlled Iodine absorption cell is mounted in front of the MIKE entrance slit, this imprints iodine spectrum referencing directly to starlight.

Professor Ivo's Amazo androids use "absorption cells" to duplicate the powers of metahumans, such as Superman's strength, Flash's speed, Batman's skills and intellect, and the abilities of Wonder Woman, Green Arrow, Aquaman, and Martian Manhunter.

Since 2001, it has been conducting a precise Doppler survey of about 300 G and K giants using a 1.88m telescope, the High Dispersion Echelle Spectrograph (HIDES), and an iodine absorption cell I2 cell at the Okayama Astrophysical Observatory (OAO).
