Advantages

Key specifications

Optical configuration: monocular (single eyepiece)
Power supply: built-in rechargeable battery for portable illumination
Intended use: observation of biological samples and educational tasks
Design: compact and mobile form factor suitable for transport

How to use

Set the microscope on a stable, level surface and insert the prepared slide on the stage. Switch on the built-in illumination using the power control and adjust battery-powered light intensity if available. Use the coarse and fine focusing controls to bring the specimen into clear view through the single eyepiece. Change magnification by rotating the objective (if multiple objectives are fitted) or by replacing the slide preparation as required. Recharge the internal battery according to the manufacturer’s instructions before extended field use.

Usage recommendations

Use clean, appropriately mounted slides and handle optical surfaces carefully to maintain image quality. Charge the rechargeable battery fully before taking the microscope into the field and carry spare slides or sample containers. For classroom use, provide basic instruction on focusing and safe handling to ensure consistent results and to protect the instrument.
