Spectroscopy is the study of the interaction between matter and electromagnetic radiation (via electron spectroscopy, atomic spectroscopy, etc). Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency, predominantly in the electromagnetic spectrum, though matter waves and acoustic waves can also be considered forms of radiative energy; recently, with tremendous difficulty, even gravitational waves have been associated with a spectral signature in the context of the Laser Interferometer Gravitational-Wave Observatory (LIGO) and laser interferometry. Spectroscopic data are often represented by an emission spectrum, a plot of the response of interest, as a function of wavelength or frequency.

IR Spectrometers (1 pcs)
Infrared spectrometry is an analytical technique used to identify and characterize chemical compounds based on their absorption of infrared radiation. It involves passing infrared light through a sample and measuring the wavelengths of light that are absorbed, which provides information about the molecular structure and functional groups present in the compound. IR spectrometry is widely utilized in various scientific fields, including chemistry, pharmaceuticals, forensics, and materials science, for compound identification, qualitative analysis, and structural elucidation.

Optical emission spectrometer (1 pcs)

Optical emission spectroscopy or atomic emission spectroscopy is a method of chemical analysis that uses the intensity of light emitted from a flame, plasma, arc, or spark at a particular wavelength to determine the quantity of an element in a sample. The wavelength of the atomic spectral line in the emission spectrum gives the identity of the element while the intensity of the emitted light is proportional to the number of atoms of the element.

Spectrometer
Spectrometers are instruments used to measure and analyze the interaction of electromagnetic radiation with matter. They provide information about the properties of materials, such as their composition, structure, and physical characteristics, by measuring the intensity or wavelength distribution of the radiation. Spectrometers are employed in various scientific fields, including chemistry, physics, astronomy, and environmental science, for applications such as elemental analysis, molecular identification, spectroscopy, and studying the properties of light.

Spectrophotometer (1 pcs)
Spectrophotometry is a technique used to measure the concentration of a substance in a solution by analyzing its absorption or transmission of light. It involves passing light of a specific wavelength through the sample and measuring the intensity of light that is absorbed or transmitted, which is then correlated to the concentration of the substance through Beer-Lambert's Law. Spectrophotometry is widely applied in fields such as chemistry, biochemistry, environmental analysis, and pharmaceuticals for quantitative analysis, enzyme kinetics, and determining the concentration of various compounds.

Spectroradiometer
Spectroradiometers are instruments used to measure the spectral distribution of electromagnetic radiation, including both the visible and non-visible regions of the electromagnetic spectrum. They provide precise measurements of the radiant power or radiant flux at different wavelengths, allowing for detailed analysis of the intensity and spectral properties of light. Spectroradiometers are widely used in fields such as lighting design, remote sensing, colorimetry, and photobiology to characterize light sources, study atmospheric properties, evaluate color accuracy, and assess the impact of light on biological systems.
