The Andonstar AD210 is an entry-level model digital microscope with a large 10.1″ display. It is mainly targeted at electronics labs where they are useful for inspecting e.g. solder joints and PCB traces or for doing high-precision soldering or repair work. Coin inspection appears to be another important use for them. Let's have a closer look.
The Andonstar digital microscopes are recognized for their economical pricing and robust performance, making them a preferred choice for electronics laboratories. They are particularly effective for inspecting solder joints and PCB traces, as well as aiding in precision soldering or repair tasks. Additionally, these microscopes are employed in numismatics for coin inspection, though they are not suitable for medical applications.
Entry-Level Digital Microscope
The Andonstar AD210, an entry-level digital microscope, features a generous 10.1″ display sans HDMI output. It is equipped with a 2-megapixel camera capable of a maximum photo resolution of 4032 × 3024 pixels (12 MPs), although it normally operates at 1920 × 1080 pixels (2 MP). Remarkably, the magnification factor, a crucial aspect of any microscope, is not detailed in any product literature or on the company's website.
Box Contents
The microscope arrives as a kit that is straightforward to assemble. The package includes everything necessary for immediate use, including a 32 GB microSD card and a USB card reader, allowing for quick photo capturing and easy transfer of images and videos to a computer. However, caution is advised when inserting the SD card, as it can be tricky and potentially hazardous.
Exploring Nature
Once assembled, the microscope can be used to examine included biological samples such as parts of a honeybee, onion, and pine. A special support with a built-in white LED facilitates illumination for these observations. This feature is not needed when examining electronic components or coins.
Lighting and Adjustment Features
The AD210 features two spotlights on flexible arms for targeted illumination, with intensity controlled via a tethered remote. Additionally, the lens includes an LED ring whose brightness is adjustable via a rotary control on the display unit. The remote also offers image brightness adjustments, distinct from the physical light settings.
Working Distance and Ergonomics
The microscope's height is adjustable, offering about 23 cm (over 10″) of clearance between the lens and the baseplate, which is sufficient for comfortable operation. The baseplate, measuring 20 cm by 18 cm, strikes a balance between working space and compactness. The microscope and display can tilt for optimal viewing angles, although adjusting these requires a wrench.
Convenience and Magnification
An infrared remote control enhances usability by providing quick access to various functions and allowing for hands-free operation to prevent disturbances during delicate adjustments.
Magnification Factor of the Andonstar AD210
By lowering the lens as much as possible and placing a PCB with an SMT component underneath, the maximum magnification potential can be observed. For instance, an 0805 SMT resistor, which measures about 2 mm in length, appears to fill the entire screen width of 214 mm, suggesting a magnification factor of around 100x.
Conclusion
The Andonstar AD210 is a versatile and budget-friendly digital microscope ideal for detailed work on electronic circuit boards and coin inspection. Its large display, ease of use, and adjustable features make it a valuable addition to any electronics lab, despite some limitations in its specification documentation.
