Vinden 75LR


The industry-leading Vinden 75LR offers high-performance thermal imaging and advanced image processing in an unmatched SWaP-C (size, weight, power, and cost) package. With multiple interfaces, video streaming, and video processing capability, the Vinden 75LR is an ideal product for integrators.


The Vinden 75LR provides continuous zoom, advanced image processing, and high-performance long-wave infrared (LWIR) thermal imaging in an unmatched small SWaP-C (size, weight, and power, and cost) package. The athermalized lens provides the benefits of both very wide (29°) and narrow (6°) horizontal fields of view (HFOV). Highly tuned one-touch autofocus operates quickly and reliably throughout the zoom range.  Two options allow short or narrow form-factors, making the Vinden 75 a superb product for integrators of unmanned ground/aerial systems and security and surveillance products.

The Vinden 75LR’s 12-µm 640 x 480 thermal imaging core utilizes a small pixel size to offer high sensitivity and high framerate video.  Paired with the core is a powerful processing engine that provides Ethernet and serial connectivity, MJPEG/H.264 encoded IP video streaming, digital zoom, electronic image stabilization, 32GB of onboard storage, and advanced image processing functions such as manual and automatic gain control, adaptive contrast control (CLAHE/LAP), target tracking and detection, and a wide array of color palettes. The LWIR camera is regulated under the U.S. EAR regulations (non-ITAR).
