Lahoux LV-21


The Lahoux LV-21 is a thermal imaging camera in the high-end range of thermal cameras of Lahoux Optics.
The light and very compact Lahoux LV-21 thermal imaging camera with 35 mm MIL specification Ophir Germanium lens can be used as a surveillance camera and by installation of a special adapter turned into a front attachment. It can be attached to various kinds of optical devices e.g. binoculars, hunting optics, camera’s or video-recorders.
The camera offers the user a solution during difficult circumstances. At night, during fog or heavy rain a hunt has to be halted. While using thermal technology, under most circumstances, continuation of the hunt is successfully possible.
The Lahoux LV-21 uses an innovative 336 x 256 sensor with 17 µm pixelpitch offering better DRI (Detection/Recognition/Identification) values and a 40 percent better resolution than older 25 µm pixelpitch sensors. DRI or the Johnson criteria, together with the NETD value (FPA sensitivity in mK) are a measure for the quality of a thermal imaging camera.
The Lahoux LV-21 camera with this sensor is better than any other commercial camera currently available on the market and gives an excellent image quality, even at greater distances.
The Lahoux LV-21 thermal imaging camera is also available in a Pro and Elite version for an even higher contrast/sharper image (higher NETD value). A waterproof universal connector can charge the camera and connect the camera to a monitor or a recorder. The Lahoux LV-21 can be used with CR-123 batteries or a 18650 rechargeable cell with polarity independent battery placement. The robust knobs are waterproof and can be operated in the winter with gloves if needed. Fast start up time and low power consumption allow the
operator to observe for a long period of time. The operating time when using the 18650 battery is very long, up to 8 hours.

DRI Values
Calculated according to the Johnson Criteria for a man sized target with a critical dimension of 1,8 x 0,5 meter. Detection, Recognition and Identification are defined for an image of respectively 1.5, 6 and 12 pixels on the image sensor.
