L101 Student Monocular Microscope (China)

The L101 student biological microscope is a monocular instrument for school laboratory observation and supervised biology practicals. Its listed interchangeable eyepieces and achromatic objectives provide total magnifications from 25× to 675×, depending on the combination used.

Place a prepared slide under the stage clips, select the appropriate optics and use the coarse and fine focus controls to explore specimen details during a practical session.

Teaching applications

For prepared-slide observation and introductory biological microscopy where the instrument meets the lesson's requirements. The mirror directs an external light source toward the specimen; built-in LED illumination is not documented.

Details to confirm before ordering

The earlier description calls the stage round while also giving 90 × 90 mm dimensions. Confirm the actual stage shape and dimensions if important to your setup. The listed fine-adjustment range of 1.4–1.8 mm and the meaning of the 45× objective's S designation should be checked against the supplied model's instructions.

Confirm inclusion of all listed eyepieces and objectives, along with any slides, cover slips or storage case. The earlier 2 kg figure is not identified as net or packed weight. Manufacturer identity and warranty terms are not specified.

Care and safety

Follow the supplier's focusing and optical-cleaning instructions. Protect lenses from dust and avoid contact between the objective and slide. Do not direct sunlight into the microscope's illumination path.
