SWIR camera has unique capabilities of material identification, and image clarity, which make it invaluable for specialized applications.
If you ask an expert about a high-end camera, the answer would be a high sensitivity SWIR camera. It is the best you can buy for industrial, surveillance, and security applications. Since you are new to this technology, you should learn about their advantages and disadvantages. It is the best camera technology, but it also has some cons.
What is SWIR technology?
It is Short-Wave Infrared (SWIR) imaging technology. It operates in 900 to 1700 nanometers wavelength and possesses unique capabilities that make them suitable for more sophisticated tasks that regular cameras can’t perform. Its capabilities go beyond visible light imaging. However, it has both pros and cons that users should learn about before investing in this technology.
Advantages of SWIR technology
1. Ability to see through obstructions and operate in low-light conditions
A SWIR machine vision camera can see through smoke, fog, dust, and other obstructions. It can even operate in extremely low-light conditions. In short, it can work where other cameras fail. For this reason, it is widely used for battlefield, surveillance, and security applications. Fixed at strategic places, these cameras can take clear pictures of the targeted areas.
2. Exceptional material differentiation
It can differentiate between metals. You should know that every metal absorbs light based on its composition. This technology can sense the difference in light absorption of metals and identify the metal under surveillance. For this reason, it is widely used in semiconductor inspection, solar cell analysis, storing packaged food items, and checking the quality of cosmetics and medicines.
3. High-resolution imaging
A compact SWIR camera can produce high-resolution images at a fast frame rate. No other technology can beat SWIR in clicking clear images, especially in low-light conditions. SWIR technology works on reflected light rather than emitted light. For this reason, it produces images with sharp edges and fine details.
Disadvantages of SWIR technology
1. High cost
SWIR is certainly the best imaging technology available in the market, but it is highly expensive. You can say that it is beyond the reach of common users. If you want to buy a SWIR camera, you should be ready to invest a huge sum in the technology.
2. Illumination
A compact SWIR camera needs some level of illumination to operate. Its performance can be reduced in a dark environment where no artificial or ambient light is available. Similarly, it may require specialized lenses, filters, or accessories to operate.
