4KAF406 is a 4K Ultra HD high magnification auto focus digital microscope with state-of-the-art SONY digital camera sensor to present 4K Ultra HD resolution motion video without lag. Designed for high magnification applications, the 4K auto focus system has a possible magnification range of 6x-1416x on 24" UHD monitor or 7x-1652x on 28" UHD monitor. 4KAF406 also has a long working distance range of 1.5” to 10.6”, which is optimal for assembly, inspection, training, real-time viewing, image capture and motion video documentation.
The 4K high magnification auto focus microscope has a microSD card that 8MP (3840×2160) jpeg images and 4K motion video can be saved directly to without requiring PC connection to the system. If preferred, the microscope can be connected to the computer through Gigabit Ethernet or USB 3.0 port. Wi-Fi connection via 5G WLAN adapter to USB 3.0 port is also available for additional cost.
4KAF406 4K high magnification auto focus digital microscope can be paired with different stands, such as basic stand, universal boom stand, or articulating arm stand. An adjustable high intensity LED ring light is included to provide bright uniform lighting, and also includes a diffuser glass filter to reduce glare when inspecting highly reflective parts. Other lighting options as well as laser pointers are also available. We also carry XY measurement stages as an alternative or supplemental option to measurement on the 4KAF406.

Function | Description |
Snap | Capture image and save it to the SD card |
Record | Record video and save it to the SD card |
Auto Exposure | When Auto Exposure is checked, the system will automatically adjust exposure time and gain according to the value of exposure compensation |
Exposure Compensation | Available when Auto Exposure is checked. Slide to left or right to adjust Exposure Compensation according to the current video brightness to achieve proper brightness value |
Exposure Time | Available when Auto Exposure is unchecked. Slide to left or right to reduce or increase exposure time, adjusting brightness of the video |
Gain | Adjust Gain to reduce or increase brightness of video. The Noise will be reduced or increased accordingly |
Red | Slide to left or right to decrease or increase the proportion of Red in RGB on video |
Green | Green is base for reference and cannot be adjusted |
Blue | Slide to left or right to decrease or increase the proportion of Blue in RGB on the video |
Auto White Balance | White Balance adjustment according to the window video every time the button is clicked |
Manual White Balance | Adjust the Red or Blue item to set the video White Balance |
Sharpness | Adjust Sharpness level of the video |
Denoise | Slide left or right to denoise the videor |
Saturation | Adjust Saturation level of the video |
Gamma | Adjust Gamma level of the video. Slide to the right side to increase gamma and to the left to decrease gamma. |
DC | For DC illumination, there will be no fluctuation in light source so no need for compensating light flickering |

Image Stitching and Extended Depth of Focus

Image Stitching (left) and Extended Depth of Focus (right)
When the 4K camera is directly connected to computer via Gigabit Ethernet port, the PC-side measurement software features image stitching as well as extended depth of focus. Image stitching allows multiple images to be pieced together to form one combined image, which is useful applications that require larger field of view while maintaining detailed image quality. Extended depth of focus allows multiple images to be stacked together so that imaging of an area with components on various planes will be all be in complete focus, creating one superior image with an extended depth of field of this single area.
4K Ultra HD has more resolution than HD 1080p
