SD VOx, 26–75mm

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

Our GEN II VOx 17μm uncooled sensor is available with a resolution of either 320×240 or 640×480 and a sensitivity able to detect differences in temperature as small as ±0.05°C. The sensor’s no-maintenance VOx design, unlike ASI and other thermal cores, is self healing and resistant to solar damage.

Germanium Zoom Lens

We pair the uncooled VOx core with our precision-engineered 26–75mm germanium zoom lens. Our germanium optics boast an industry-leading ƒ/1.0 aperture, compared to most others at ƒ/1.6. This means they allow more thermal energy to reach the sensor, further increasing its range and performance.

Extreme 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 the 75mm ƒ1.0 lens and the built-in Dynamic Image Contrast Enhancement (DICE) for increased contrast and image clarity, this system is capable of detecting vehicles up to 7km away or humans at distances up to 2.3km.* 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.
