If you’re like most people, you probably think of infrared lights as something used for night vision. But did you know that these special lights have a wide range of other uses? From medical therapies to security systems, infrared lights are essential for a variety of purposes. In this blog, we’ll explore some of the most interesting uses for these versatile lights.
Infrared lights and heat lamps
Infrared lights are used for a variety of purposes, including but not limited to:
- Heating: Infrared light is used in many industrial and commercial settings for heating purposes. For example, it is used to heat food, such as in a food warming drawer, or to heat people, such as in a sauna.
- Incubation: Infrared light is sometimes used to incubate eggs.
- Analytical chemistry: Infrared light can be used to identify different compounds based on the way they absorb light of different wavelengths.
- Therapy: Some types of infrared light are used in physical therapy to relieve pain or increase blood circulation.
Infrared light therapy
Infrared light therapy is a type of treatment that uses infrared light to heal the body. It has been used to treat a variety of conditions, including wrinkles, acne, and chronic pain. The therapy works by increasing blood circulation and metabolism, which promotes healing.
Infrared light therapy is a relatively new treatment option, and more research is needed to determine its efficacy. However, many people who have used the therapy report positive results.
Infrared saunas
Infrared saunas are a type of sauna that uses light to create heat. This form of sauna is becoming increasingly popular, as it has many health benefits.
One of the main benefits of using an infrared sauna is that it can help you to lose weight. As the heat penetrates your body, it causes you to sweat and this helps to flush out toxins from your body. It also helps to boost your metabolism, which means you will burn more calories.
Infrared saunas can also help to relieve pain. The heat helps to increase blood flow and circulation, which can reduce inflammation and pain in the muscles and joints. It can also help to reduce stiffness in the muscles and improve the range of motion.
In addition, infrared saunas can also have a positive effect on your mental health. The heat can help to relax the body and mind, and it can also help to improve sleep quality. The relaxation that comes with using an infrared sauna can also help to reduce stress levels and promote a sense of well-being.
Infrared security cameras
Infrared security cameras are becoming increasingly popular because they offer a number of advantages over traditional security cameras. For one, they don’t require any external lighting, which means they can be used in a wider range of locations. Additionally, infrared cameras can see in the dark, which makes them ideal for 24-hour surveillance.
Infrared astronomy
Infrared astronomy is the branch of astronomy and astrophysics that studies astronomical objects visible in infrared (IR) radiation. The wavelength of infrared light ranges from 0.75 to 300 micrometers. It overlaps with both thermal imaging and near-infrared spectroscopy.
Early discoveries in infrared astronomy include cosmic background radiation, Infrared Bodies (planets and asteroids which are not visible to the naked eye because they reflect very little visible light), Betelgeuse (the first star whose surface temperature was measured), and interstellar dust clouds (which block visible light but allow infrared).
Infrared spectroscopy
One of the most important uses of infrared light is in infrared spectroscopy, also known as fourier transform infrared spectroscopy (FTIR). This technique is used to identify and study chemicals by their absorption of light in the infrared region of the spectrum.
Different chemicals absorb different wavelengths of light, so by looking at the pattern of absorption, it is possible to identify a substance. Infrared spectroscopy is used in a wide range of applications, from quality control in manufacturing to forensic analysis and environmental monitoring.
Infrared thermography
Infrared thermography (IRT), thermal imaging, and thermal video are examples of infrared imaging science. Thermographic cameras detect radiation in the infrared range of the electromagnetic spectrum (EMS) and produce images of that radiation, called thermograms.
Since infrared radiation is emitted by all objects with a temperature above absolute zero according to their black-body radiation emission curve, thermography makes it possible to see one’s environment with or without visible illumination. The amount of radiation emitted by an object increases with temperature; therefore, thermography allows one to see variations in temperature.
Infrared applications in the military
The U.S. military uses night vision devices (NVD) that detect infrared (IR) light to give soldiers the ability to see in low-light and nighttime conditions. IR technology is also used in target acquisition systems, which direct weapons to their targets, and in guidance systems, which help missiles find their targets.
In Closing
As you can see in this post, there are many important applications for infrared light technology that benefit society.
