It detects scratches, bumps and burrs. Suitable for QC stations in 3C electronics, new energy and mold industries to realize visual inspection and data recording.

Daily Maintenance of the Electron 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.

How to Choose a Model

Frequently Asked Questions

Q1: Is it necessary to connect a PC to operate the GP-820T coaxial microscope?

A1: No. The unit can be directly connected to a monitor via HDMI for real-time viewing, photo capture and video recording. A computer is only required for optional advanced operations like software measurement and data export, ideal for on-site quick inspection.

Q2: What industrial inspection applications is the GP-820T coaxial microscope suitable for?

A2: It is designed for high-reflection flat samples such as semiconductor chips, polished hardware parts, glass covers and precision molds, detecting tiny defects including scratches, chipping and micro textures that are hard to see with naked eyes.

Q3: What benefits does the stand and base bring during inspection work?

A3: The heavy metal base and vertical lifting stand deliver stable placement and good vibration resistance. The focusing knob has well-balanced damping for fine lens height adjustment, perfect for long-hour continuous quality control in factories.

Q4: Compared with ordinary ring lights, what is the advantage of coaxial illumination when inspecting highly reflective samples?
