Product Applications

Application Scope: Suitable for visual defect inspection of large PCB boards, castings, molds, new energy assemblies, sheet metal parts and large plastic components. Widely used in equipment maintenance, assembly inspection, hardware processing and auto parts testing. The long arm design allows observation inside cavities and flexible scanning over large samples.

Difference from conventional body-mounted microscopes

Difference from ordinary articulated microscopes: Most standard articulated stereo microscopes only support image preview without independent 4K output and software measurement functions. This Articulated Long-Arm Stereo Microscope adopts trinocular optical path to synchronize eyepiece viewing and screen display. HDMI direct output enables real-time viewing without a PC, while USB connection supports professional dimension measurement. The long arm stand offers larger adjustment range, paired with 7–45X continuous zoom for both large-area scanning and close-up detail inspection. Compared with ordinary articulated microscopes, it integrates digital measurement and 4K imaging for more complete functions.

Technical Specifications

26-171For which products is this detection range suitable?

Daily Maintenance of the Microscope

· Optical Lens & Coaxial Light Window Care: Only use professional optical lens tissue or microfiber dust-free cloth to clean the lens and coaxial light optical window. Never use paper towels or rough cloth to avoid scratching optical coating. For fingerprints and oil stains, apply a small amount of optical cleaner to the cloth. Do not drip liquid directly onto optical components. Avoid touching optical surfaces with bare hands.

· Camera, Lens Barrel & Stand Maintenance: Clean the HD camera, monocular zoom barrel and metal column with dry dust-free soft cloth. Do not expose the unit to water. Keep alcohol, acetone and other strong corrosive solvents away to protect paint and printed marks. Keep HDMI and power connectors dry to prevent metal oxidation and poor contact. Do not pull signal cables forcibly.

· Stage & Focus Mechanism: Remove dust from the black stage with dry soft cloth. Clean dust on focus knobs and column guide rails regularly. A small amount of dry grease can be applied. Liquid lubricants are forbidden, to prevent oil dripping and contaminating coaxial light module and lens. Operate the focus knob gently, do not turn it forcibly to avoid gear damage.

· Power & Operating Environment: Use the original power adapter. Place the equipment in dry, low-dust environment, away from high temperature, humidity and heavy vibration. Power off and unplug power and HDMI cables when not in use for a long time.
