Comparison With Other Options
| 10X eyepiece for ST30 ST40 series | The 15X eyepiece provides higher magnification for finer detail inspection, while the 10X offers a wider field of view and lower magnification for locating components. |
|---|---|
| 20X eyepiece for ST30 ST40 series | The 15X offers a balance between magnification and field of view; the 20X increases magnification but reduces the field of view to 10mm. |
| Generic 15X eyepiece from another brand | This eyepiece is specifically designed for ST30 and ST40 series microscopes with correct tube diameter and optical alignment, ensuring compatibility and image quality. |
Use Guide
- Ensure the microscope is powered off and the head is secured before replacing the eyepiece
- Align the eyepiece with the 23.2mm tube diameter and gently twist until it clicks into place
- Check that the eyepiece is fully seated and does not wobble before use
- Clean the lens surface with a soft cloth before and after use to prevent dust or oil residue
- Store the eyepiece in a protective case when not in use to prevent damage
