See what remains hidden from our eyes
The ace 2 X visSWIR cameras offer superior image quality in both visible and short-wave infrared spectrums. Compact and cost-effective, they excel in applications like penetrating complex structures or detecting hidden objects, where conventional SWIR cameras are too large or expensive.

Our ace 2 X visSWIR cameras combine the high image quality of a cooled SWIR camera with the size and price of an uncooled SWIR camera.
SWIR sensors (short wavelength infrared, or SWIR) based on InGaAs technology tend to have pixel defects that become visible as white dots in the image. A longer exposure time or increased sensor temperature intensify this effect. Therefore, cameras with cooling are often used, resulting in a detrimental effect on the size and price of the SWIR cameras.
Images without pixel defects thanks to Pixel Correction Beyond
Pixel defects, common in InGaAs sensors, can negatively affect image processing. Pixel Correction Beyond, a dynamic defect pixel correction technology, is a key factor behind the exceptional image quality of our SWIR cameras.
This feature uses an algorithm we developed to dynamically detect and correct pixel defects in real-time within the camera's FPGA, ensuring that image content remains distortion-free. The image comparison highlights its impact at a sensor temperature of 35°C and an exposure time of 50 ms, demonstrating how Pixel Correction Beyond significantly minimizes pixel defects.
More about Pixel Correction BeyondHomogeneous background thanks to Line Noise Reduction
In order to achieve the same excellent image quality with the SWIR cameras with VGA or 1.3 MP resolution (IMX991 or IMX990) as with the high-resolution SWIR cameras, these models feature Line Noise Reduction.
This feature minimizes background noise, which is visible as horizontal stripes in the image, in real time and thus ensures a more homogeneous background.
Optimal image quality—even for longer exposure times—thanks to external cooling
The image quality of InGaAs sensors decreases significantly with increasing exposure time and sensor temperature. For applications with longer exposure times of over 10 milliseconds, it can therefore make sense to reduce the sensor temperature using external cooling in order to obtain optimal image quality.
Our cooling solutions combined with our advanced image processing algorithms significantly improve the signal-to-noise ratio (SNR) and thus the image quality. This means that you get excellent images even with longer exposure times of up to 1 second.
Our external cooling systems work without fans. As a result, you retain all the advantages of an uncooled camera over a camera with integrated cooling, including: low space requirement, an attractive price, and lower power consumption. In addition, they ensure stable image acquisition without vibrations and are ideal for use in cleanrooms as there is no air turbulence.

Capabilities of the ace 2 X visSWIR cameras
The ace 2 X visSWIR cameras detect light in both the visible and short-wave infrared range (SWIR). In the SWIR range with wavelengths from 0.9 µm to 1.7 µm, many materials have different optical properties. This opens up new application fields.
Look below the surface
Due to the longer wavelength, short-wave infrared light penetrates some materials, causing them to appear transparent. This allows SWIR cameras to see what lies beneath the surface. For example, bruises on fruit and vegetables can be detected, fill levels can be checked in otherwise opaque containers, and semiconductors can be inspected for defects.
Temperature detection
Hot surfaces (from approx. 140°C) emit light in the short-wave infrared range, which is why SWIR cameras are used to measure or estimate the temperature of objects. The intensity in the image is directly related to the temperature. This property can then be used to monitor thermal processes, such as the inspection of welding seams.
Typical application fields in the SWIR spectral range
The variety of applications for vision systems in the SWIR spectral range extends from semiconductor inspection and recycling to quality inspection and sorting of food products.
