A1: Built with coaxial illumination optical path, light hits the sample surface vertically. It is specially designed for reflective planes such as metal, wafers and glass, capturing scratches, pinholes, tiny circuits and other flat defects that are hard to see with ordinary ring lights.
A2: It delivers native 4K output up to 3840×2160. It supports real-time live view, photo capture and video recording. Combined with software, it can perform precise dimension measurement and save inspection records.
A3: It adopts a heavy metal base and vertical lifting stand. The solid base reduces shaking. The lifting knob has proper damping to lock lens height steadily, ideal for long continuous quality inspection work.
A4: Ring light illuminates samples from the side, which tends to cause reflection and shadow. Coaxial light projects light vertically onto surfaces. It reduces reflection interference on highly reflective samples and reveals subtle flat defects clearly.
A5: It can connect directly to a monitor for live view, capture photos and record videos without a computer. When connected to a PC, advanced features including software measurement and data export become available for different inspection scenarios.

· 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.
