The Micron VG-3 Junior Microscope builds on the reliable VG-2 platform and adds a focusable Abbe condenser (N.A. 1.25) with iris diaphragm, allowing precise control of illumination and focus for better contrast and clarity during observation.
It retains the sturdy educational design with a triple revolving nosepiece carrying 10× and 40× achromatic objectives, providing clean and colour-corrected images for routine biological study.
The microscope uses a plano concave mirror illumination system, enabling operation without electrical power. Smooth adjustment is provided by separate coarse and fine focusing knobs, while the fixed 110 × 110 mm stage with stage clips keeps slides stable during examination.
With its straight monocular viewing tube and choice of 10×/15× Huygens or 10× wide-field eyepiece, the VG-3 offers comfortable viewing and improved optical control compared to basic entry-level models, making it ideal for higher school and college practical work.
