4K Ultra High-Magnification Digital Microscope

Gaopin GP-307-4K 4K Measuring Microscope. This 4K Ultra High-Magnification Digital Microscope features parfocal zoom from 95X to 614X, the highest magnification model in this series. It is equipped with a 4K camera and premium monocular zoom lens. Heavy base structure effectively suppresses vibration. Built-in measurement system supports measurement of micro features, photo and video storage. Designed for high-magnification observation and dimension inspection of ultra-small workpieces.

Difference from conventional body-mounted microscopes

Difference from ordinary microscopes: Standard digital microscopes can hardly reach stable magnification around 600X and suffer from vibration and defocus at high power. This High-Magnification Electron Microscope achieves 95–614X parfocal zoom without repeated focusing. Optimized optical lens maintains sharpness at high magnification. Heavy base reduces vibration. It is specially built for micron-scale sample inspection and outperforms ordinary digital microscopes.

Daily Maintenance of the Electron Microscope

· Optical Lens Care: Only use professional optical lens tissue or microfiber dust-free cloth to wipe lens surfaces. Never use paper towels or rough cloth to avoid scratching lens coating. For fingerprints and oil stains, apply a small amount of optical cleaner to the cloth. Do not drip liquid directly onto the lens. Avoid touching the optical surface of the lens by hand.

· Camera, Lens Barrel & Stand Maintenance: Clean the 4K camera, zoom barrel and metal column with dry dust-free soft cloth. Do not expose the whole unit to water. Keep alcohol, acetone and other strong corrosive solvents away to protect paint and printed marks. Keep all connectors dry to prevent metal oxidation and bad contact.

· Stage & Dual Light Source Care: Remove dust from the white stage and upper & lower LED dual light ring with dry soft cloth. Clean the light window in the same way as the lens, do not use corrosive liquid. Do not pull the light cable forcibly.

· Focus Mechanism Maintenance: 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 lenses, light sources and samples. Operate the focus knob gently, do not turn it forcibly to avoid gear damage.

· Power & 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 the adapter when not in use for a long time.
