It is common that thermal cameras oriented for long-range detection often suffer from overweight problems. This is because, in imaging instruments, a substantial volume of electromagnetic radiation must be allowed to reach the sensor. longer focal lengths therefore must be compensated through larger lens apertures to ensure sufficient radiation exposure, thus long-range thermal camera lenses are often made into large diameters, leading to massive weights and enormous dimensions. The problem is less severe in the case of MWIR lenses than LWIR lenses because a higher f-number is tolerable to the more sensitive cooled detectors matched with MWIR lenses. However, the long detection range of MWIR thermal camera CZ lenses with focal lengths within the approximate range of 100-1000mm claiming to be lightweight in the market, in general, weighs between 5-8kg. In practice a little increment of weight could be of great adverse impacts, for example, increasing power consumption, reduction of the moving velocities, etc.
With the unceasing efforts of the engineering team, Shalom EO has achieved a technical breakthrough in developing an Ultra-Lightweight 90-1100mm f/5.5 Continuous Zoom MWIR Thermal Imaging Camera Lens Module. The 223mm diameter, 295.51mm length CZ Lens assemblies weigh 4.2 kg, providing an unrivaled comprise between long focal lengths and weight issues. This MWIR lens module with built-in motorized focus mechanics and electronics indicates a technical breakthrough in our research and exploration of light weights, compact, high-performance thermal camera imaging lenses. The lenses are excellent when assigned to various missions requiring long detection ranges and high thermal contrast, such as Counter-Unmanned Aerial Vehicle (C-UAV/C-UAS).
Our 90-1100mm f/5.5 CZ MWIR Lenses feature dense integration of optomechanical integration with optical capabilities maximized to the outermost point which the dimension and weight issues would permit. MTF and image qualities are optimized to keep the image sharp and crisp during the zooming process.
The smooth continuous zooming mechanisms of Shalom EO’s 90-1100mm f/5.5 CZ MWIR Thermal Imaging Camera Lenses deliver flexible switching of different FOVs between focal lengths from 90mm to 1100mm. At 90mm, a wide FOV of a maximum of 6.11° Horizontal and 4.89° Vertical is accessible to obtain a general broad view. At 1100mm, a narrow FOV of a minimum of 0.5° Horizontal and 0.4° Vertical could be procured to concentrate large amounts of pixels on fewer targets to generate more details. Furthermore, the accurate focus is maintained over the entire focal length range, facilitating the locking on your targets.
Shalom EO also provides other MWIR Continuous Zoom Lens Modules of manifold focal length ranges and f-numbers.
