26–75mm Uncooled Thermal Camera

Thermal cameras, unlike traditional visible cameras, use heat rather than light to see an object. Humans, animals, and vehicles are very hot in contrast to most backgrounds making trespassers hiding in shadows or bushes easy to spot. Thermal images are unaffected by bright light and have the ability to see through atmospheric obstructions such as smoke, dust, and light fog. This makes it an ideal technology for a number of applications, including but not limited to surveillance and security, search and rescue, fire response, marine and land navigation, and wide area situational assessment.

LWIR VOx Thermal Imager

Infiniti uses cutting-edge 12μm LWIR VOx uncooled thermal sensors with resolutions of 384×288, 640×512 or 1280×1024 HD. The 12μm pixel pitch provides a narrower field of view without changing the lens. This means we are able to achieve 40% further range than 17μm and 25% further range than 15μm sensors while delivering a sensitivity of 0.05°C. The sensor’s no-maintenance VOx design, unlike ASI and other thermal cores, is self healing and resistant to solar damage.

Continous Zoom Lens

We pair the uncooled VOx core with our precision-engineered 26–75mm germanium lens. The 2.8X optical zoom range offers a 16.8° to 5.9° horizontal field of view using the 640×512 sensor (other FOVs shown below), and pixel detail as high as 6.25ppm at 1 kilometer. This lens boasts a large f/1.0 aperture, which allows up to 2.3 times more heat to reach the sensor than the standard f/1.5–f/1.6 apertures used in the rest of the industry. This results in higher sensitivity, sharper images, and longer ranges making LWIR one of the most cost-effective long-range imaging solutions.

Long-Range Detection

Our 26–75mm Uncooled Thermal Camera is a Long-Wave Infrared (LWIR) camera which means it operates on 7,000nm–14,000nm wavelengths where terrestrial temperature targets emit most of their infrared energy. Using our 26–75mm continuous zoom ƒ1.0 lens and the built-in Dynamic Image Contrast Enhancement (DICE) for increased contrast and image clarity, this camera is capable of detecting vehicles up to 6.8km away or humans at distances up to 2.9km.* While thermal is a significant investment, its superior range and performance allows it to replace and outperform other solutions, making it a viable option for many applications.
