Can LWIR cameras measure precise temperatures?

Yes, Xenics LWIR cameras are calibrated to provide accurate temperature measurements for specific applications, making them valuable for tasks like industrial monitoring and medical diagnostics. On the other hand, real-objects have varying emissivity profiles, and atmospheric conditions can affect the information. To get precise temperatures, one shall take into account for the true material emissivity and atmospheric transmission properties.

What is the difference between cooled and uncooled thermal cameras?

Cooled thermal cameras use a cooling system to enhance sensitivity and image quality, making them suitable for more demanding applications. On the other hand, the uncooled thermal cameras offering more compact and energy-efficient features that suitable for different dynamic applications.

What is a long-wavelength infrared (LWIR) or thermal camera?

A LWIR or thermal camera is a digital camera exclusively designed to captures the infrared radiation in the range between 8 to 14 µm, allowing it to create images based on temperature differences. 

Can SWIR cameras detect hidden objects or substances?

SWIR cameras in principle are able to detect hidden objects or substances by revealing differences in material composition that are not visible in the visible spectrum. This feature makes the SWIR cameras valuable in security and inspection applications.

Are SWIR cameras sensitive to heat like thermal infrared cameras?

SWIR cameras are not as sensitive to heat as thermal infrared cameras. They primarily capture reflected or emitted light in the short-wavelength infrared range, rather than relying on heat signatures as thermal cameras detect.

Can SWIR cameras see through materials that are opaque to visible light?

Definitely! SWIR cameras can see through some materials that are opaque to visible light, such as certain plastics and silicon. This feature makes the SWIR cameras be useful for semiconductor industry for inspecting materials and processes.

What are the applications of SWIR cameras?

SWIR cameras can be used in various applications, including industrial inspection, medical imaging, agriculture, surveillance monitoring, and scientific research. Furthermore, SWIR cameras are particularly useful for tasks such as material analysis, moisture detection, and seeing through certain types of fog coming from particles of water for example or smoke.

What is a short-wavelength infrared (SWIR) camera?

A SWIR camera operates in the short-wavelength infrared spectrum, typically covering wavelengths from approximately 900 to 1700 nanometers. This specific type of camera is mainly used for imaging beyond the visible spectrum but shorter than the thermal camera.

How does the image intensifier tube work in a UV camera?

The image intensifier tube amplifies low-intensity UV light by converting photons into electrons and then multiplying them before converting them back into visible light. This results in a brighter and clearer image, especially in low-light conditions.
