What Is a Spectroscope?
A spectroscope is a device that separates light components in order to measure only the intensity of light at the wavelength of interest from synthetic light of various wavelengths mixed together.
Recently, many spectroscope have integrated a detector of the separated light, and the entire process from light separation to detection mechanism is sometimes collectively referred to as a spectroscope
Uses of Spectroscopes
Spectroscopes are used in all industries and research fields because they can, in principle, spectrate light sources in various wavelength bands, from radio waves to radiation, regardless of whether they are reflected or transmitted light, and not only visible light.
In the field of analytical chemistry, it is used to measure the intensity of sunlight and plasma luminescence, and is also used to evaluate optical properties such as reflectance of materials.
They are also often incorporated without awareness into quality control lines that detect reflected light or other arbitrary wavelengths in product inspection lines using light sources such as lasers.
Principle of Spectroscopes
Generally, to spectrate a light source, it is first necessary to shape the light.
After setting the light resolution by passing the light source through a gap called a slit, the light source is collimated by a collimator made of lenses and mirrors.
Spectroscopy can be performed by passing this collimated light into spectroscopes. There are two types of spectrographs: a diffraction grating type that uses the diffraction phenomenon of light and a prism type that uses the refraction phenomenon of light.
In the diffraction grating type, the wavelength and resolution of light that can be detected can be changed by changing the diffraction pattern, since spectroscopy is performed using the reflection of light reflected by diffraction gratings engraved at regular intervals on the surface of the monochromator.
The principle of a diffraction grating type monochromator is explained here using a figure.
There are two types of diffraction gratings: transmission and reflection. Figure 1 shows a conceptual diagram of a reflection-type diffraction grating. When collimated light from a light source (white light) containing light of various wavelengths is incident on a diffraction grating, multiple gratings, or grating-like structures (G1, G2, ...), are formed at each position. When collimated light from a white light source (white light) is incident on a diffraction grating, diffraction of reflected light in a wide angular direction occurs at the respective positions of multiple gratings, or grating-like structures (G1, G2...). Here, interference of light occurs, and monochromatic light, in which only a specific wavelength λ is intensified, is emitted in the angular direction (θ) where the optical path difference (dsinθ) of the reflected light originating from each grating satisfies a predetermined condition (integer multiple of wavelength λ).
In this way, different wavelengths are dispersed (separated in a rainbow-like pattern) at different angles by the diffraction grating (see Figure 2).
Furthermore, by using the slit shown in Figure 2, only monochromatic light of a specific wavelength can be extracted from the dispersed reflected light. This is the principle of a diffraction grating type monochromator. By rotating the grating, it is possible to change the wavelength of the light to be extracted.
How to Select a Spectroscope
When using a detector-integrated spectroscopes, it is necessary to select an appropriate one for the wavelength of the light source measured.
For example, if the light source is in the range from ultraviolet to near-infrared, a CCD is fine, but if the light source is longer wavelength than that, an InGaAs type detector is necessary.
As mentioned in the measurement principle, the wavelength of a diffraction grating type monochromator is determined by the diffraction pattern, so it is necessary to select one suitable for the wavelength of interest.
The resolution of a prism type spectroscopes are determined by the nature of the prism, but it has the feature of no loss of light intensity, so it is advisable to choose the right one depending on the application.
How to Use Spectroscopes
The general procedure for using an analytical instrument with spectroscopes are as follows.
- Determine the substance to be measured and the wavelength range to be measured.
- Select spectroscopes corresponding to the wavelength you wish to measure.
- Shine a light on the substance and spectrate the desired wavelength.
- Put the desired light into the sensor to detect the signal.
- The obtained signal is converted to a spectrum.
If it is an expensive object used in a laboratory, spectroscopes called a Michelson interferometer automatically detects the wavelength of a specific light. Even small, portable machines can detect the wavelength of interest by passing the light transmitted or reflected through the material through interchangeable spectroscopes.
The resulting wavelengths enter the sensor (detector) and are detected as a signal for each wavelength. This signal is converted into a waveform called a spectrum, and by analyzing this spectrum, the state of matter is analyzed.
Examples of Spectroscopes Experiments
There are several examples of experiments using spectroscopes, depending on the wavelength to be measured.
For example, the following are examples of experiments in each wavelength range, starting from the short wavelength side.
- X-ray spectroscopes identifies the composition of a material's surface by shining x-rays on the surface and passing the reflected light through the spectroscopes
- UV/visible spectroscopes identify the components of the object and the amount contained by passing light through the material.
- Infrared spectroscopes reveal the structure of a substance by shining light on the bonds between molecules.
Thus, the information obtained depends on the wavelength range of the spectroscopes.
Spectra Obtained From Spectroscopes
The purpose of using spectroscopes are to acquire information from an unknown or known substance and analyze it to identify the state of the substance. The final spectrum obtained from the spectroscopes, called a spectrum, is the waveform diagram used for this analysis.
The spectrum obtained from spectroscopes includes the following examples. By first defining the information you want to know, it is important to select the appropriate spectroscopes to acquire the spectrum.
X-ray spectroscopes identify atoms from the peaks of the characteristic X-rays being measured.
UV/visible spectroscopes detect the energy difference between the electrons excited when light is transmitted through a sample as a spectrum.
The infrared spectroscopes detects the vibrational energy between the bonds connecting atoms as a spectrum.
