Review NIKON Plan Dic 10x 0.25 210/0 Microscope Objective Lens Great Condition

The **Nikon Plan Diotar 10x/0.25 210/0 microscope objective lens (Part No. 220987)** is a precision-engineered optical component designed for high-performance microscopy, offering exceptional clarity, durability, and versatility in both research and industrial applications. Part of Nikon s renowned Plan Diotar series, this objective lens combines advanced optical design with robust mechanical construction to deliver consistent, high-resolution imaging across a wide range of sample types. With a **10x magnification** and a **numerical aperture (NA) of 0.25**, it excels in low-to-medium magnification tasks, providing a balanced field of view (21 mm) while maintaining excellent optical correction for minimal chromatic and spherical aberrations. The **210/0** designation indicates its working distance of **21 mm**, making it ideal for examining thick or opaque specimens without the need for immersion techniques, such as oil or water. This objective is particularly well-suited for brightfield, phase contrast, and differential interference contrast (DIC) microscopy, where its flat-field design ensures uniform illumination and sharp imaging across the entire field of view. Constructed with **high-quality glass elements** and coated with Nikon s proprietary **UVI (Ultra Violet Inhibiting) and AR (Anti-Reflective) coatings**, the lens minimizes light loss, glare, and color fringing, enhancing contrast and resolution for more accurate observations. The durable **metal housing** and precision-ground optics are designed to withstand frequent use in demanding environments, while the **parfocal design** ensures seamless integration with other Nikon objectives and infinity-corrected microscope systems. Whether used in biological research, materials science, or quality control, this objective lens provides reliable performance, making it a valuable addition to any high-end microscopy setup.

### **Pros and Cons of buying a Nikon Plan Fluor 10x/0.25 (210/0) Objective Lens (Part No. 220987)**

1. **Compatibility with Nikon Microscopes** This is an original Nikon objective lens, designed specifically for Nikon microscopes, ensuring proper optical alignment and parfocality with other Nikon objectives in the same series.

2. **High-Quality Optics** Nikon s Plan Fluor series is known for its sharp, flat-field imaging, reducing distortion and improving resolution. The 10x magnification is versatile for general use, including brightfield and phase-contrast applications.

3. **Long Working Distance (210mm)** The extended working distance (0.25 NA) allows for greater flexibility when imaging thick specimens or using additional accessories like cameras or manipulators.

4. **Durability and Reliability** Nikon objectives are built to last, with robust construction and precise manufacturing, reducing the risk of optical degradation over time.

5. **Compatibility with Nikon Infinity Optics** If your microscope uses an infinity-corrected optical path (common in modern Nikon systems), this lens will integrate seamlessly.

6. **Standard Magnification** A 10x objective is a fundamental part of most microscope setups, making it a practical addition for routine observations, teaching, or general laboratory work.

7. **Corrected for Common Aberrations** The Plan Fluor design minimizes spherical and chromatic aberrations, providing clearer images across the field of view.

1. **High Cost** Nikon objectives, especially high-quality ones like this, are expensive compared to third-party or lower-end alternatives. The price may not justify the purchase if you only need occasional use.

2. **Limited Magnification** At 10x, this lens is not ideal for high-resolution imaging (e.g., cell biology or detailed tissue analysis). Higher-magnification objectives (e.g., 20x, 40x) are often more useful for critical work.

3. **Low Numerical Aperture (NA 0.25)** A lower NA means less light-gathering ability and lower resolution compared to higher-NA objectives (e.g., 0.4, 0.65). This may limit performance in low-light conditions or when imaging fine details.

4. **Potential Overkill for Basic Use** If you primarily use a microscope for simple tasks (e.g., examining slides in a classroom or general inspection), a lower-cost, lower-magnification lens (e.g., a 4x or 5x) may suffice.

5. **Compatibility Issues with Non-Nikon Systems** If your microscope is not Nikon, this lens will not work without significant modifications or adapters, which may void warranties or compromise performance.

6. **Maintenance and Care Requirements** High-quality lenses require careful handling to avoid scratches or dust contamination. Improper cleaning or storage can degrade performance over time.

7. **Market for Used Lenses** While this lens is likely in good condition, used Nikon objectives can sometimes be found at a discount. If budget is a concern, checking the pre-owned market may offer better value.

### **Conclusion**

The **Nikon Plan Fluor 10x/0.25 (210/0) objective lens (220987)** is a high-quality, reliable choice for users with Nikon microscopes who need a versatile, flat-field low-magnification lens. Its strengths lie in its optical precision, compatibility with Nikon systems, and durability, making it ideal for general use, teaching, or applications where a long working distance is beneficial. However, its high cost, limited magnification, and lower NA may not justify the purchase for users with specific high-resolution needs or those working with non-Nikon equipment.

- **Have a Nikon microscope** and need a reliable 10x objective for routine work,

- **Prioritize optical quality and longevity**, or

- **Require a long working distance** for specialized applications,

- **Need higher magnification or resolution**,

- **Work with non-Nikon systems**, or

- **Are on a tight budget**,

consider alternatives such as lower-cost third-party lenses, used Nikon objectives, or a different magnification range.

### **Recommendation**

- You are certain of its compatibility with your Nikon microscope.

- You value Nikon s optical reputation and need a durable, flat-field 10x objective.

- The long working distance is essential for your workflow.

- You require higher magnification or resolution for detailed imaging.

- Your microscope is not Nikon-compatible.

- You can achieve similar results with a lower-cost alternative (e.g., a used lens or a different brand).

For most general users, this lens is a **solid, long-term purchase** but weigh the cost against your specific needs before committing. If possible, test it in your setup or consult with a microscope specialist to ensure it meets your requirements.
