    640 × 480 Thermal Detector

    The TU620 uses a 640 × 480 thermal detector with a 12 μm pixel pitch.

    This sensor configuration may support:

    • Detailed thermal images

    • Improved separation between nearby heat sources

    • Better image quality during digital zoom

    • Clearer observation of smaller thermal subjects

    • More usable detail at longer viewing distances

    Actual image performance depends on weather, atmospheric humidity, temperature contrast, focus, image processing, and display quality.

    Vanadium Oxide Sensor

    The detector uses uncooled vanadium oxide technology and operates within the listed 8–14 μm infrared spectral range.

    An uncooled detector supports:

    • Fast startup

    • Compact construction

    • Lower power consumption

    • Reduced mechanical complexity

    • Portable thermal observation

    NETD ≤30 mK

    The listed thermal sensitivity is 30 mK or lower.

    A lower NETD value generally indicates an improved ability to distinguish small temperature differences, which may provide clearer images in:

    • High humidity

    • Fog

    • Light rain

    • Low thermal contrast

    • Uniform backgrounds

    • Changing environmental conditions

    The exact test method, lens configuration, and processing mode should be confirmed.

    25 mm F1.0 Objective Lens

    The 25 mm F1.0 objective lens is designed to provide a relatively wide field of view for scanning and short- to medium-distance observation.

    It may be useful for:

    • Broad-area outdoor scanning

    • Property inspection

    • Wildlife observation

    • Search support

    • Equipment checks

    • Building inspection

    Detection and recognition ranges should be added only when supported by verified manufacturer test data.

    Base Magnification and Digital Zoom

    The TU620 provides approximately 1.4x base optical magnification with digital zoom from 1x to 8x.

    The zoom may be available in fixed steps such as:

    • 1x

    • 2x

    • 4x

    • 8x

    Digital zoom enlarges the displayed image but does not increase the detector’s native resolution. Fine detail may decrease at higher zoom levels.

    Wide Field of View

    The listed field of view is approximately:

    • Horizontal: 17.46°

    • Vertical: 13.14°

    This relatively wide view can help users locate heat sources and scan larger areas more efficiently.

    50 Hz Refresh Rate

    The 50 Hz refresh rate supports smooth thermal-image presentation during:

    • Handheld scanning

    • Walking observation

    • Subject tracking

    • Machinery inspection

    • Outdoor monitoring

    • Property checks

    Final image smoothness also depends on processor and display performance.

    Manual Focus

    The objective lens uses manual focusing.

    Manual focus allows the user to refine image clarity for different observation distances.

    The minimum focusing distance and focus-ring range should be confirmed before publication.
