The Kelvin 350 and Corona 350 series are 35 cm (14”) gimbals housing the infrared core from the FLIR Systems 660 series of infrared cameras, a HD or SD daylight video camera, and a high resolution digital still frame camera. Gimbal weight varies between 24.5 to 27 kg (54 to 59.5 lbs) depending on payload selection.

In addition to the infrared, daylight video, and digital photo camera, the Corona 350 also includes an UV camera for the detection of faults induced by Corona discharges in high voltage power structures.

• Lightweight high stiffness composite body
  The gimbal is build from high stiffness composite materials and aluminum inner structure insuring the lowest weight possible.
• Airworthy and Environmetally Tested
  The system is tested to RTCA-DO-160E Environmental standards thus assuring increased reliability and flight safety. All products hold EASA airworthiness approvals.
• 4 axis active stabilization
  The design is four axis active gyro-stabilized based upon very low drift fiber-optic gyroscopes and a digital servo motor control system and a patented two axis linear isolator. This unique design offers outstanding stability ensuring easy steering and accurate imaging independent of aircraft movements.
• UV camera detects Corona in broad daylight
  The corona camera is capable of detecting and producing video images of the energy generated by the corona phenomena. Corona and arcing occur by stress of the electric field which is not current dependent and therefore can only be revealed by UV inspection. The camera is highly sensitive,  3 x 10-18 watt/cm2, and fully solar-blind meaning that Corona can be visualized in full daytime. The camera contains the UV detector to image the corona and a color Day TV to image the surrounding scene. The signals from the two sensors are blended together and presented to the operator. The three field of view lens (16º /  8º / 4º) permits long range detection and close up analysis of Corona.
• Radiometric infrared camera
  The thermal imaging camera can easily identify objects from their thermal signature or power line problems where the fault is apparent as a change in temperature. The camera contains a high definition 640×480 pixel detector that allows temperature readings either in real time or from a stored image. It delivers exceptional sensitivity, resolution, and image quality for a wide variety of airborne imaging applications. Its 0.03°C sensitivity and ±1°C accuracy means precise temperature readings.
• MegaPixel Digital Photo camera
  The MegaPixel camera captures high resolution still images that provide visual records of faults detected by the infrared camera.
• GPS Tagging
  GPS data is stored as part of each captured image file name thus permitting geo-referencing of fault locations, areas where animals are roaming….
• Advanced infrared software
  The interface can transfer 16-bit radiometric data directly into the onboard PC for post-flight analysis of captured infrared images. FLIR’s Reporter Professional software permits retrieval and analysis of IR images and temperature data. It includes temperature display and analysis functions such as isotherms, line profiles, area histograms, and much more.
