Key specifications
Optical magnification: up to 300×
Illumination type: integrated LED with adjustable intensity
Optical configuration: compound microscope with multiple objective lenses
Viewing head: options for monocular or binocular viewing (model-dependent)
Focus system: coarse and fine adjustment controls

How to use
Place the microscope on a stable, level surface and connect the power source if required. Mount a prepared slide on the mechanical stage and secure it with the stage clips. Start with the lowest-power objective lens and center the area of interest using the stage controls. Use the coarse focus knob to bring the specimen into general focus, then refine the image with the fine focus knob. Adjust the LED illumination intensity to achieve a clear contrast without glare. Switch to higher-power objectives as needed, refocusing each time with fine adjustments.
Usage recommendations
For classroom use, begin lessons with the lowest magnification to familiarize students with specimen orientation and stage controls. When observing stained slides or delicate samples, reduce light intensity to avoid bleaching or overheating. Regularly clean lenses with appropriate lens tissue and keep the mechanical stage free of dust to maintain image quality.
