Electronics & rework
Solder joint inspection, BGA rework verification and connector checks — the polarizer kills glare from lead-free solder and flux residue.
Cut the cable, keep the detail. A true 2-megapixel handheld microscope that streams 1080P over WiFi to phones and tablets — or plugs into a PC over USB — with a switchable polarizer for glare-free imaging of metal, solder and glossy surfaces.
The UB-DM023A was designed around a simple observation: inspection does not happen at a desk. A technician under a machine, a jeweller at a trade show, a teacher walking between benches — none of them want a cable dictating where they can stand. So the DM023A connects wirelessly to the phone or tablet already in their pocket, and keeps a wired USB mode for the bench when they sit down.
Under the housing is a genuine 2-megapixel CMOS sensor with an optical glass lens — no interpolated magnification numbers, no software upscaling pretending to be detail. What you count on the datasheet is what resolves on screen.

Solder joint inspection, BGA rework verification and connector checks — the polarizer kills glare from lead-free solder and flux residue.
Coin grading, hallmark reading, gemstone inclusions and watch movements — wireless operation suits trade shows and shop counters alike.
One unit projected to a whole classroom, or packed into a field kit — no outlet, no laptop, no setup ritual.
iOS 12 or later, Android 4.2 or later over WiFi, and Windows 7/8/10/11 plus macOS 11 or later over USB. In practice that covers well over 90% of phones, tablets and computers in the field today.
Yes. OEM starts with laser-etched logo, custom gift box, printed manual and a branded app splash screen. Full ODM — enclosure changes, firmware defaults, ISP tuning and a fully customised application — is available for volume programmes. See the software page for app and SDK options.
The UB-DM050U trades wireless freedom for higher resolution and is happiest fixed to a bench. The DM023A wins when the inspection has to move. Many distributors stock both — tell us your use case and we will recommend honestly.
5MP USB microscope for the bench — 50–250×, highest resolution in the range.
