Parity | None |
Ensure the correct software is used and click to open.

Select the Serial Port (UART) option and enter the Settings interface.
Select the correct COM port number, set the baud rate to 115200, and click Connect. A prompt box will pop up to indicate a successful connection.

Select either Black Hot or White Hot image polarity mode.
Controls the analog image output.
Controls the image freeze function.
Select different integration times based on different temperature ranges (H: High; N: Normal; L: Low).
Select the corresponding magnification factor to achieve center magnification.
After vertical image flip, correction is required.
Note: When starting up to display an image or adjusting the integration time, a uniformly surfaced object (e.g., A4 paper) must be used to cover the lens portion for background correction.

8-bit: Outputs 8-bit video data after AGC;
14-bit: Outputs data after non-uniformity correction.
OFF: Disables camera-link output;
ON: Enables camera-link output.
Select output frame rate: 25Hz, 50Hz, 100Hz.
When using a gas detector, the default mode is Variable Frame Rate, where the frame rate varies with the integration time
1. If background correction is not performed, the background may be incorporated into the image during startup or integration time changes; background correction is required.

2. Select a uniformly surfaced object to cover the lens or the camera core window portion. Simultaneously, select Background Correction in the software. Click it, wait a few seconds, then remove the object; correction is complete.

The K Coefficient Enable button controls the K function switch. The Normal Temperature K Coefficient requires two temperature ranges from blackbodies for image calibration. It is recommended that the high-temperature range be between +40℃ and +55℃, and the low-temperature range be between 0℃ and +20℃.
Calibration Procedure:
a) Power on and wait for the image to appear normally. In Basic Settings -> Image Mirror, select Normal mode. Enter the K Coefficient page to collect parameters.
b) Place the camera core in front of a blackbody set within the +40℃ to +55℃ range. Click Collect B1 to perform the first parameter collection.
c) Place the camera core in front of a blackbody set within the 0℃ to +20℃ range. Click Collect B2 to perform the second parameter collection (positioning the core similarly as above).
d) Click Generate K Coefficient.
e) Click Background Correction to perform background correction and check the K coefficient effect.
f) If satisfied with the K coefficient effect, click Save K Coefficient to save the parameters.
g) If not satisfied, repeat the above steps.

2. Dead Pixel Replacement
a) Click the Crosshair button to enable the dead pixel crosshair.
b) Use the slider and enter numbers to control the horizontal and vertical coordinates:
X controls the horizontal coordinate, Y controls the vertical coordinate.
c) Click Center to return the crosshair to the screen center.
d) Click the Dead Pixel Enable button to turn dead pixel replacement on/off.
e) Use the dead pixel crosshair to mark the dead pixel at its center. Click the Dead Pixel Repair button to fix it, or click the Undo Repair button to undo the dead pixel repair

3. Auto Find Dead Pixels
a) Users can activate the Auto Find Dead Pixels function if they find that dead pixels still exist or have increased on the core.
b) Observe a surface with uniform appearance and significant temperature difference. After locating a visible dead pixel, click + or – to fine-tune the position and repair it.
c) Set a matching threshold between 30 and 100, click Start Find to automatically locate dead pixels; the changes take effect immediately.
d) Check if dead pixel replacement was successful. If satisfied, click Save Dead Pixels. Otherwise, repeat the above steps.

MWIR technology is an infrared imaging technology that operates in the 3–5 μm waveband. It is widely used in advanced defense imaging systems, providing critical capabilities such as surveillance, target detection, and data collection.
Under certain conditions, MWIR cameras can detect objects up to approximately 2.5 times farther than LWIR cameras. Additionally, MWIR is less sensitive to atmospheric effects, making it particularly effective in environments with good visibility and favorable weather conditions.
MWIR is highly sensitive to temperature differences and excels at detecting high-temperature targets such as engines or missile plumes. Its strong thermal contrast enhances imaging performance, making it well‑suited for precise detection in highly dynamic scenarios.
Our Mid-Wave Infrared (MWIR) lens offers a wide range of optical solutions to enhance your thermal imaging system. They are designed to meet a wide range of detection, recognition, and identification requirements . Available as optional accessories, the lineup includes continuous zoom lenses covering ranges from 15‑300mm up to 60‑1200mm with aperture options of f/4.0 or f/5.5 depending on the model.
