Thermally stabilized precision aspheric lenses
The optical scheme consists of aspherical germanium components and is characterized by a high light output and a practically diffraction-limited image quality that is uniform over the entire field of view. The lens design ensures precise movement of all internal elements and perfect image sharpness in all focus and temperature ranges. The lens DLC coating enables high IR light transmission and protects the surfaces from scratches and damage.
Proprietary methods of digital image processing
Proprietary software and original digital image processing algorithms include: a unique system of dynamic contrast adjustment, automatic correction of brightness and contrast that does not prompt the user to respond to changing environmental conditions, and a system of small elements as well as the background which is not influenced by their temperature difference. All of these functions enable thermal signature images with a resolution that goes to the limit.
Automatic sensor calibration system
The automatic shutterless sensor calibration system continuously optimizes sensor performance in the event of changing observation conditions and does not distract the observer from manual settings, controls or recalibrations. It is completely noiseless and is best suited for continuous observation.
Specifications
The multifunctional thermal imaging device with laser range finder Dedal-380 T2 Quest LRF can be used as an autonomous observation device or together with day binoculars or a spotting scope. The device enables a quick and precise distance measurement to a heat signature in complete darkness and in all weather conditions.
Dedal-380 T2 Quest LRF is intended to be mounted in front of a daylight device for observation in all lighting and weather conditions, including total darkness, heavy rain, snow or fog.
The low weight and the size of the plug-on attachment enable mounting on the objective lens of a daylight device directly via a push-on ring adapter.
The clip-on is equipped with a connection for video recording and switching to an external power source. It works fully automatically and does not require any additional adjustments to changing environmental conditions. The start time is less than 3 seconds. A high level of detail of the target image and its background, both cold and warm objects, is the distinguishing feature of the clip.
