25X Biological 23.2mm Microscope Eyepiece
The 25X Biological Microscope Eyepiece is an achromatic eyepiece with a 23.2mm outside diameter, designed to fit most standard biological microscopes.
Product Overview
The 25X Biological Microscope Eyepiece is an achromatic eyepiece with a 23.2mm outside diameter, designed to fit most standard biological microscopes. It provides 25X magnification and enhances image clarity without requiring a full instrument upgrade. It is suitable for routine inspection, teaching, and documentation tasks where higher magnification is needed without changing the objective lens.
- Magnification25X
- Optical designAchromatic
- Mounting diameter23.2mm
- Standard compatibilityDIN/JIS
- Lens typeSingle lens with coating
- Focus mechanismNone; relies on microscope focus controls
Key Benefits
- 25X magnification extends the total system magnification without replacing the objective
- 23.2mm outside diameter fits most standard biological microscopes with DIN/JIS compatibility
- Achromatic design reduces chromatic aberration for clearer images at higher magnification
- Low-cost upgrade to increase inspection detail without buying a new microscope
- Maintains compatibility with existing objectives and camera systems on the same stand
Application Scenarios
- Increasing magnification for detailed inspection of cell structures in a biology lab
- Enhancing visibility during teaching demonstrations where students need to see fine details
- Improving clarity in routine quality checks of biological samples under a standard biological microscope
- Supporting documentation tasks where higher magnification is needed for image capture
- Replacing a worn or missing eyepiece without changing the microscope's optical configuration
Who It Is For
- Teaching laboratories in schools and universities using biological microscopes
- Clinical and research labs performing routine sample inspection
- Quality control teams in pharmaceutical or biotech labs needing consistent magnification
- Educational suppliers maintaining multiple microscope setups with interchangeable parts
- Users upgrading a standard biological microscope for better detail without full replacement
Problems It Solves
- A standard 10X eyepiece limits the total magnification when higher detail is needed
- Replacing an entire microscope to get higher magnification is costly and unnecessary
- Worn or missing eyepieces disrupt inspection workflows and reduce image clarity
- Incompatible eyepieces from other brands prevent use in standard microscope systems
- Lack of a high-magnification option forces operators to rely on lower power objectives
Technical Features
- Achromatic optical design to reduce color fringing
- 25X magnification power for increased detail
- 23.2mm outside diameter for compatibility with standard microscope tube fittings
- DIN/JIS standard size for use across most biological microscopes
- Designed for use with 10X objectives to achieve 250X total magnification
- Single lens system with coated optics for improved light transmission
- No internal focusing mechanism; relies on the microscope's coarse and fine focus

Comparison With Other Options
| 10X biological eyepiece | The 25X eyepiece increases total magnification from 100X to 250X with a 10X objective, enabling finer detail inspection without changing the objective or stand. |
|---|---|
| 30X biological eyepiece | The 25X offers a lower magnification than 30X, reducing eye strain and field of view reduction while maintaining better compatibility with standard 23.2mm tube diameters. |
| Widefield 10X eyepiece | The 25X provides higher magnification than a standard 10X, but has a narrower field of view and requires more precise focusing. |
Use Guide
- Ensure the microscope tube diameter is compatible with 23.2mm eyepiece mounting before insertion
- Insert the eyepiece gently into the microscope head to avoid damaging the lens or tube
- Use with a 10X objective to achieve 250X total magnification; adjust focus using the microscope's coarse and fine knobs
- Clean the lens surface with a soft cloth before use to avoid dust or smudges in the image
- Avoid touching the lens surface with fingers to prevent oil residue and image degradation

What is the magnification of this eyepiece?
25X. When used with a 10X objective, it provides 250X total magnification.
What is the outside diameter of the eyepiece?
23.2mm. This matches the standard DIN/JIS size used in most biological microscopes.
Is this eyepiece compatible with my biological microscope?
Yes, if your microscope uses standard DIN/JIS 23.2mm eyepiece tubes. Most common biological microscopes support this size.
Can I use this with a 4X or 40X objective?
Yes. With a 4X objective, it gives 100X total magnification. With a 40X objective, it gives 1000X total magnification.
Does this eyepiece have internal focusing?
No. It is a fixed-focus eyepiece; focus is controlled entirely by the microscope's coarse and fine focus knobs.
Is the lens coated?
Yes. The single lens is coated to improve light transmission and reduce glare.
