Comparison With Other Options
| XUP301 Polarizing Microscope | The XUP300 includes a 60x (S) objective and a 360° rotatable stage with 6' vernier; the XUP301 lacks the 60x objective and has no vernier on the stage. |
|---|---|
| XUP302 Polarizing Microscope | The XUP302 includes a 6V/30W halogen lamp and 3W-LED lamp as standard; the XUP300 has these as optional accessories. |
| Standard biological microscope | A standard biological microscope lacks polarizing components, analyzer, Bertrand lens, and λ slip, so it cannot perform birefringence or conoscopic analysis. |
Use Guide
- Adjust the interpupillary distance between 48mm and 75mm before focusing to ensure a single merged image
- Use the 1° divisions and 6' vernier on the stage to align crystal axes or grain boundaries precisely
- Remove the Bertrand lens and analyzer for single polarizing observation when needed
- Insert the λ slip or quartz wedge to measure birefringence and retardation in transparent materials
- Use the C-mount adapter with focus adjustment to attach a camera for documentation
- Ensure the polarizing unit is properly aligned with the condenser for transmitted light observation

Frequently Asked Questions
What is the maximum magnification with the 60x objective?
With a 10x eyepiece, the total magnification is 600x. Higher magnifications are possible with optional eyepieces.
Can I use this microscope for transmitted and reflected polarized light?
Yes. The polarizing unit and analyzer are designed for transmitted light. For reflected light, a suitable mirror or beam splitter must be added.
Does the stage have fine angular control?
Yes. The stage rotates 360° with 1° divisions and a 6' vernier for precise angular positioning.
What is the purpose of the Bertrand lens?
The Bertrand lens enables conoscopic observation, allowing the visualization of interference figures in birefringent materials.
Can I add a camera to this microscope?
Yes. A C-mount adapter with focus adjustment is available as an optional accessory for camera integration.
What is the difference between XUP300 and XUP301?
The XUP300 includes a 60x (S) objective and a stage with 6' vernier; the XUP301 has only up to 40x (S) and no vernier on the stage.
