The latest evolution in Sierra-Olympia Technologies’ Ventus line, the Ventus Micro 225, has been introduced as a cooled mid-wave infrared camera engineered specifically for demanding airborne and mobile applications.
Designed to maximize both performance and longevity, the system is built around a High Operating Temperature (HOT) sensor that operates between 140K and 150K. This sensor is paired with a linear cooler design, a combination intended to significantly increase durability in the field. This architecture results in an extended cooler life of more than 18,000 hours. The design also reduces vibration and utilizes fewer moving parts, which are critical advantages for mission-critical deployments where mechanical stability is essential.
Regarding optical capabilities, the unit features a 640×512 detector array with a 10µm pitch. It is equipped with an 18-225mm f/3.6 continuous zoom lens, providing a 12.5x zoom factor. The field of view ranges from 20 degrees at the wide end to 1.6 degrees at the narrow horizontal setting. Additional optical features include motorized focus and zoom capabilities, as well as a hard carbon-coated front element with environmental sealing to protect the lens in harsh conditions.
The camera adheres to a “Camera as Component” philosophy, maintaining a low-SWaP (Size, Weight, and Power) design approach. This allows the Ventus Micro 225 to integrate seamlessly into gimbals and various enclosures. To support diverse integration needs, the system is available with multiple output configurations, including Sightline 4000 processing (HDMI, SDI, IP/Ethernet), USB, or custom solutions tailored to specific program requirements.
