Move freely, the motherboard without lag, the picture is smooth and clear without any trailing or delay2. This camera makes a breakthrough by supporting an external thermal imaging signal source; the optical image and temperature distribution are displayed in real time and synchronously on the screen, making the temperature characteristics clear at a glance3. Say goodbye to multi-screen switching, micro-morphology and temperature distribution are presented on the same screen. The camera innovatively realizes the synchronous display of optical images and thermal imaging images on a single screen4. Support thermal imaging signal access+dual-channel microphone audio pickup, let your scientific research, testing, and teaching not only see clearly, but also hear and measure accurately5. The microscope camera redefines the operation experience with a one-click design, a physical photo-taking key and video-recording key, no need to rely on computer clicks, just press with your finger and it responds immediately6. More powerful hardware and software algorithms, HDR wide dynamic range make the image clearer and more realistic, with a higher degree of reproduction.7.
