Infrared Spectroscopy Market - Strategic Insights and Forecasts (2026-2031)

Infrared Spectroscopy Market Size:

The Global Infrared Spectroscopy market is forecast to grow at a CAGR of 5.8%, reaching USD 1.64 billion in 2031 from USD 1.24 billion in 2026.

Infrared (IR) spectroscopy studies the electromagnetic spectrum's infrared section, which includes light with a longer wavelength and lower frequency than visible light. The notion of IR spectroscopy can be broadly studied in three ways: first by measuring reflection, then by emission, and finally by absorption. The global IR spectroscopy market is primarily driven by industries such as food and beverage, pharmaceutical, and chemical, where it is utilized to identify functional groups in molecules and quantify the relative abundance of each type of group. IR spectroscopy can also be used to determine the strength of intermolecular forces and to examine reaction dynamics.

Infrared Spectroscopy Market Growth Factors:

• Food safety issues

Unsafe food containing hazardous bacteria, viruses, parasites, or chemical substances causes more than 200 diseases ranging from diarrhoea to cancer (Source: World Health Organization). According to WHO, unhealthy food costs low- and middle-income nations US$ 110 billion in lost productivity and medical costs each year. Food safety is consequently a big priority for governments all around the world. Infrared spectroscopy is one of the most regularly utilized analytical techniques in food quality monitoring and control. According to NeoSpectra, the NeoSpectra LabStore has the greatest collection of NIR calibration models. NIR spectroscopy analyses a wide range of foods, including animal feed, cereals, agricultural products, flour milling, and pet food, as well as polymers, chemicals, and other substances. Agriculture, food, and beverage testing, as well as chemical and industrial processes, are examples of applications.

• Mid-infrared spectroscopy has numerous uses in a variety of industries.

Mid-infrared (MWIR) spectroscopy is one of the most important segments of the IR spectroscopy market, and it is expected to develop at a rapid rate throughout the projected period. MWIR spectroscopy is used in process analysis and quality control in a variety of industries, including food and beverage, pharmaceuticals, chemicals, and oil and gas. Because of the increasing need for this technology in various applications such as process control, quality assurance, and failure analysis, the research, and development industries are expected to contribute significantly to the growth of the Mid-infrared spectroscopy market. IRsweep develops, manufactures, and sells optical spectroscopy products in the mid-infrared based on semiconductor quantum cascade laser frequency comb technology. Sensirion's optical sensing technology portfolio increases with this acquisition, from components and modules to stand-alone infrared spectrometers for industrial and research applications, which will assist IRsweep's infrared spectrometers in expanding their reach and addressing new applications.

In the smartphone market, IR spectroscopy will witness rapid expansion in the application of Face ID. Facial recognition technology, together with sophisticated fingerprint scanners, is now a standard feature of smartphone security. While not necessarily more secure than a fingerprint scanner, biometric ideas like facial recognition are faster and more convenient to use. The estimated false acceptance rate on most mobile devices today is typically less than one in a thousand. 3D IR depth mapping is by far the most secure method of facial recognition technology now available on the market. Unlike traditional camera-based solutions, 3D IR technologies are not deceived by photos and are faster and more reliable than notions such as iris scanning.
