10X/16mm Biological Microscope Eyepiece
The 10X/16mm biological microscope eyepiece is an achromatic eyepiece with a 23.2 mm outside diameter, designed to fit most standard biological microscopes.

Product Overview
The 10X/16mm biological microscope eyepiece is an achromatic eyepiece with a 23.2 mm outside diameter, designed to fit most standard biological microscopes. It provides 10X magnification with a 16mm field of view, enhancing image clarity and detail without requiring a full instrument upgrade. This component-level accessory allows users to improve inspection resolution at low cost.
- Magnification10X
- Field of view16mm
- Optical designAchromatic (DIN/JIS standard)
- Outside diameter23.2 mm
- Mounting size23.2 mm (in diameter)
- CompatibilityMost common biological microscopes with DIN/JIS standard tube size
Key Benefits
- 10X magnification extends the total system magnification when paired with objectives
- 16mm field of view provides a wider viewing area than standard 10mm eyepieces
- 23.2 mm outside diameter fits most common biological microscopes with DIN/JIS standard tube size
- Achromatic design reduces chromatic aberration for clearer images at higher magnifications
- Low-cost upgrade to improve inspection detail without replacing the entire microscope
Application Scenarios
- Replacing a worn or low-magnification eyepiece in a teaching lab microscope
- Upgrading a basic biological microscope for higher resolution in a clinical or research setting
- Matching a new eyepiece to an existing microscope when replacing a damaged or missing component
- Improving field of view during routine histology or cytology slide examination
- Using in a quality control lab where consistent magnification and clarity are required
Who It Is For
- Teaching laboratories in schools and universities using biological microscopes
- Clinical and veterinary labs performing routine slide inspections
- Research labs requiring consistent magnification across multiple microscopes
- Quality control departments in pharmaceutical or biotech manufacturing
- Users maintaining or upgrading older biological microscopes without replacing the full system
Problems It Solves
- A low-field-of-view eyepiece limits the area visible at once, slowing inspection and increasing eye strain
- Outdated or damaged eyepieces reduce image clarity and introduce distortion
- Requiring a full microscope replacement to achieve higher magnification or better resolution
- Mismatched eyepiece diameter causing improper fit or alignment in the microscope head
- Lack of interchangeable eyepieces that match the DIN/JIS standard across different microscope brands
Technical Features
- Achromatic optical design to reduce chromatic aberration
- 10X magnification for use with standard objectives
- 16mm field of view for improved visibility of specimen area
- 23.2 mm outside diameter for compatibility with DIN/JIS standard microscope tubes
- Standard size for use with most biological microscopes in the market
- New, unused component with consistent optical performance

Comparison With Other Options
| 10X/10mm biological microscope eyepiece | The 10X/16mm eyepiece offers a wider field of view, reducing the need to move the slide during inspection and improving workflow efficiency. |
|---|---|
| 10X/20mm biological microscope eyepiece | The 10X/16mm eyepiece has a smaller field of view but maintains better edge sharpness and is more compatible with standard microscope tube sizes. |
| Non-achromatic 10X eyepiece | The achromatic design reduces color fringing, especially at higher magnifications, improving image clarity and accuracy. |
Use Guide
- Ensure the microscope tube diameter matches the 23.2 mm specification before inserting the eyepiece
- Insert the eyepiece gently into the head until it clicks into place, avoiding force that could damage the lens
- Clean the lens surfaces with a soft lens cloth before use to avoid dust or smudges affecting image quality
- Use with objectives that provide total magnification within the microscope's working range
- Check alignment with the ocular lens and focus adjustment to ensure a clear, centered image
