Types of Spectroscopy Equipment

Spectroscopy pertains to the study of the interaction of matter with radiated energy. The visible light gets disperses as per its wavelength, i.e. by prism and spectroscopy originated through it. With the progress of time it encompassed any type of interaction with radioactive energy.

Here, three types of spectroscopy equipment have been discussed in detail. Broadly, spectroscopy is the study of energy and matter using measurement tools. Some of the earliest spectroscopy was done on visible light using prisms; this has evolved into numerous new and technologically advanced fields that examine all the different aspects of energy-matter interaction. Spectroscopy is used in scientific fields ranging from medicine to planetary science.

Transient spectroscopy is used in the detection of electrical defects in semiconductors. It is primarily an experimental tool, utilized in studying the particulars of a defect and how concentrated in the semiconductor they are. There are multiple types of this type of spectroscopy, all used to investigate different aspects of defects. The most common is deep-level spectroscopy, in which a polarization voltage is disrupted by a voltage pulse. This lowers the electric field in the area, allowing charged particles from the semiconductor bulk to enter the defect area and fix the non-equilibrium charge state. This technique is very sensitive and effective.

Thermal spectroscopy is regarded as the most useful spectroscopy equipment. It is an offshoot or subset of infrared spectroscopy, and it measures the amount of radiation emitted in the infrared part of the light spectrum. The difference between this type of spectroscopy and other spectroscopy disciplines is that it mainly concerns energy emitted from an object, rather than reflected or transmitted. This distinction makes it particularly useful in the detection and study of exoplanets, which are planets outside this Solar System. These cameras are often present on radio telescopes or orbiting spacecraft, and can be used to determine planetary surface composition through analysis and comparison to previously tested materials.

Electrical spectroscopy (also dielectric spectroscopy or electrical impedance spectroscopy) is primarily used in order to determine the dielectric properties of an object or medium. It has a second, experimental use in electrochemistry, where it is used primarily in order to measure impedance of a system effectively. This can often allow the experimenter to determine such properties as energy storage as well as dissipation. It is an effective experiment for a number of mediums, even biological tissue. Many different mechanisms, such as dipole relaxation and electronic polarization, help to contribute as to how a system or substance utilizes electrical charges and can help in electrochemical equations in order to determine the rate limiting step.
