Zeiss Plan-Apochromat 40x/0.95 Korr Infinity-Corrected Microscope Objective 420660-9970
Product Description
The Zeiss Plan-Apochromat 40x/0.95 Korr Microscope Objective 420660-9970 offers advanced optical performance for high-resolution microscopy applications including fluorescence analysis and brightfield imaging. Designed for use with infinity-corrected optical systems, this dry objective features a numerical aperture (NA) of 0.95, providing excellent light-gathering capability and high image contrast essential in biomedical engineering, molecular diagnostics, and bioprocessing research.
Key Technical Specifications:
- Magnification: 40x
- Numerical Aperture: 0.95
- Free Working Distance: 0.25 mm
- Coverglass Thickness Compatibility: 0.13 – 0.21 mm, suitable for standard cover slips
- Thread Type: M27x0.75
- Immersion: Dry objective (without immersion medium)
- Field of View Diameter: 25 mm
- Parfocal Length: 45.06 mm
- Optical System: Infinity Color Corrected System (ICS)
- Color Correction: Apochromatic (APO) for minimal chromatic aberration
- Iris: None (no diaphragm adjustment)
Applications:
- Widely used in fluorescence microscopy with excellent image clarification
- Suitable for brightfield imaging in cell biology, histology, and clinical diagnostics
- Compatible with Differential Interference Contrast (DIC) techniques for enhanced contrast without staining
- Not optimized for phase contrast, darkfield, or material/reflected light microscopy
Performance and Quality Assurance:
Each objective is thoroughly inspected, cleaned, and tested on a Zeiss Observer 7 microscope by specialized technicians. Verification includes optical quality assurance under both brightfield and fluorescence conditions, mechanical lubrication for adjustable components, and confirmation of smooth operation, ensuring reliability in demanding research workflows.
Benefits for Biotechnology and Molecular Biology:
This Plan-Apochromat objective is critical for molecular imaging workflows, synthetic biology research, and bioprocessing applications where high numerical aperture and color accuracy enable precise cellular and sub-cellular visualization. Its compatibility with fluorescence modalities makes it an essential tool in gene editing studies and molecular diagnostics, supporting high-resolution live-cell imaging.
Packaging and Support:
Professionally packed for safe shipping, the product includes a warranty and access to expert technical support post-sale, providing researchers with confidence and long-term serviceability.
This objective is widely adopted in synthetic biology research and critical in biopharmaceutical production pipelines requiring rigorous microscopy standards.
