I. Product Overview
The DM-SZ series includes two core models: DM-SZ7 (including DMSZ7P) and DM-SZ8. These are integrated video microscopes launched by ABN. They integrate a continuous zoom optical lens, high-definition camera module, LED ring light and touch display unit. The microscope body provides unified power supply, greatly reducing wiring harnesses. The DM-SZ7 features a zoom range of 0.7–5X (7:1 zoom ratio), equipped with a 4-megapixel CMOS sensor and a 10-inch IPS touchscreen. The DMSZ8 offers more than 33% larger object field of view compared with DMSZ7. It adopts a 2-megapixel CMOS sensor paired with a 12-inch 1920×1080 screen and supports a frame rate of 60fps. Optional 0.5X/1X/1.4X main objectives are available to extend the total magnification. The 225mm long-travel focusing mechanism accommodates samples of varying heights. It supports HDMI/USB output and storage expansion, and is widely applied in electronic quality inspection, precision assembly, scientific research and teaching. The DM-SZ series all-in-one video microscopes adopt a compact and elegant design, integrating continuous zoom optical lenses and high-definition digital cameras. The microscope body supplies power to the display, camera and ring light in a unified manner, effectively solving wiring harness issues. Users may select versions with or without a display as required. Compared with traditional optical microscopes, the DM-SZ series has advantages such as digital magnification, convenient observation, easy data storage and intelligent operation. It notably reduces fatigue during prolonged use and aims to deliver a more user-friendly and comfortable operating experience.

III. Functional Features
Integrated design and simplified power supply: Optics, camera, display and lighting are integrated. The mirror unit adopts unified power supply with fewer wiring harnesses, space-saving layout and easy mobility. Configurations with or without a screen are available.
High-definition imaging and smooth display: DMSZ7 uses a 4-megapixel CMOS (30fps+), while DMSZ8 adopts a 2-megapixel CMOS (60fps). It delivers high contrast and low noise, supports real-time HDR, and enables convenient operation via OSD menus.
Wide zoom range and flexible focusing: DMSZ7 features a zoom range of 0.7–5X, and DMSZ8 provides a wider field of view. It has a focusing travel of 225 mm and a maximum working distance of 170 mm, compatible with samples of various heights.
Intelligent segmented illumination: Equipped with a ring light containing 56 LEDs. The inner and outer rings can be controlled independently. Oblique lighting combined with near-coaxial light improves recognition of fine details, with adjustable brightness to suit samples made of different materials.
Data management and expandability: Supports multi-interface output including HDMI and USB. It comes with built-in storage and allows expansion via SD card or USB flash drive. The measurement software can measure parameters such as length and area for easy data archiving and traceability.
