Frequently Asked Questions
Q1. What type of microscope is the BM-2, based on its visible construction?
The BM-2 is a junior student compound microscope designed for basic slide-based observation. Its vertical optical tube, revolving nosepiece, and flat stage clearly indicate use with prepared slides rather than surface or dissection work.
Q2. How suitable is this microscope for school-level practical learning?
The design is clearly intended for students, with a stable curved arm, simple controls, and limited magnification range. It supports routine classroom experiments such as observing plant tissues, basic cells, and simple microorganisms without overwhelming beginners.
Q3. What does the monocular head indicate about viewing style and usage time?
The monocular head allows observation through a single eyepiece, which is common in student microscopes. It is suitable for short to moderate observation sessions during practical classes, though it is not designed for long-duration professional analysis.
Q4. What can be understood about magnification capability from the visible objectives?
The microscope shows two objective lenses mounted on a revolving nosepiece, indicating basic low and medium magnification levels. This setup is appropriate for learning fundamental microscopic structures but not for high-resolution or advanced biological research.
Q5. How is illumination handled, and what limitation does it introduce?
The microscope uses a mirror-based illumination system beneath the stage to reflect external or natural light. While this keeps the design simple and durable, light intensity depends on ambient conditions and cannot be finely controlled.
Q6. What does the overall build suggest about durability and maintenance for student use?
The solid metal frame, simple focusing knobs, and minimal electronic parts suggest good durability for regular classroom handling. Maintenance is straightforward, mainly involving lens cleaning and keeping the mirror and stage free from dust.
