New 25 mm IIT

Exosens is proud to announce the expansion of its Photonis Ultimate Detection Scientific Imaging product portfolio with the introduction of the 25 mm Image Intensifier solution.

How can a user control the mechanical shutter to assure the image?

Within LWIR cameras, it is a factory default, the shutter is initialized when the temperature at the detector changes by 0.5°C. An additional timing elapse function is also implemented and can also be activated. When a camera has just been started it will get to his working temperature. During this time the detector will warm-up and will be shuttered several times to assure the quality of the image.

What is a shutter in a camera?

A shutter is a part within a camera that controls the light exposure that reaches the sensor. There are two main shutters, namely mechanical shutter and electronic shutter. The mechanical shutter is physical curtain of the camera that open and close to expose the sensor. While the electronic shutter works by turning the sensor's sensitivity on and off for specific durations.

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.
