The DTI 6/40 Thermal Imaging Camera have a 40mm f/1.0 lens that provides a thermal detection range of 2,180 yards and a field of view of 570' at 1,000 yards. That's a 11° x 8.2° angular view (horizontal x vertical). Need more field of view and less range? You could get the DTI 6/20 or just purchase the 20mm f/1.0 lens as well and exchange them as the need arises. With the 20mm lens, you get half the range and double the field of view. With the DTI 6/40 configuration you get a base magnification of 3x and digital zoom from 3.0x to 30x in 0.1x increments using the scroll wheel.

ZSIP Pro image processing algorithm is an advanced technology found only in DTI 6 models. It uses a 3-phase optimization process that divides the image into several tiles, enhances the contrast in each and merges them into one complete image. This results in a higher contrast, sharper image, all within a few nanoseconds.

Zeiss Smart Image Processing

Thermal images are typically dark and have difficulty separating warm temperatures from cool ones, resulting in a low contrast image. You can see this in the "Undesired Image" below. The Zeiss Smart Image Processing (ZSIP) software optimizes the thermal image to improve contrast and distinguishable detail into a "Desired Image".


Color Mode Comparison

All DTI models now have eight available color modes which can be chosen via the menu. Each color mode has advantages over the others, some in contrast, some in lowering eye fatigue, and some in finding the thing you're looking for.
