Comparison With Other Options
| Traditional biological microscope with separate camera and monitor | The A300 integrates the screen, camera, storage and power, so no external devices are needed for basic observation and documentation. |
|---|---|
| Digital microscope with only USB output and no screen | The A300 includes a 7-inch HD screen for direct viewing and on-site analysis, eliminating dependency on a computer. |
| Microscope with fixed illumination only | The A300 supports bottom, side and coaxial illumination, enabling observation of transparent, reflective and opaque samples without changing setups. |
Use Guide
- Turn on the microscope by pressing and holding the multi-functional key; release to power off
- Use the double-layer stage to position samples precisely in two axes before observation
- Select the appropriate objective lens (2x to 100x) based on the sample type and required magnification
- Use the measurement function by calibrating the scale in the software before analyzing samples
- Connect the HDMI output to an external monitor or recorder for larger display or recording
- Recharge the 10400mAh battery when the unit shuts down automatically after inactivity

What is the maximum magnification available?
The optical magnification range is 30x to 1500x, using objectives from 2x to 100x. Digital magnification adds up to 3x.
Can I use this microscope without a computer?
Yes. The A300 has a built-in 7-inch HD screen, camera, storage and battery, so it operates independently.
Does it support video recording?
Yes. It captures HD video at 1080p/30fps and stores it internally or outputs via HDMI.
How long does the battery last?
The 10400mAh battery supports extended use, but actual runtime depends on screen brightness, illumination use and frequency of capture.
Can I measure sample dimensions on screen?
Yes. The included software supports scale calibration and real-time measurement of sample features.
What types of samples can I observe?
The A300 supports biological slides, metallographic samples, insects, leaves, and other real-world objects using bottom, side or coaxial illumination.
