Zeiss Plan-Apochromat 40x/0.95 Korr Infinity-Corrected Microscope Objective 420660-9970

The Zeiss Plan-Apochromat 40x/0.95 Korr Microscope Objective (Part No. 420660-9970) is a precision-engineered infinity-corrected lens optimized for advanced microscopy applications in biotechnology, molecular diagnostics, and biomedical engineering. Designed for use with Zeiss Observer 7 microscopes, this dry objective features:

• Magnification: 40x for detailed cellular and subcellular imaging
• Numerical Aperture (NA): 0.95, enabling high resolution and excellent light-gathering capability critical in fluorescence analysis and live-cell imaging
• Free Working Distance: 0.25 mm, suitable for standard coverglass thickness (0.13 - 0.21 mm)
• Optical System: Infinity Color Corrected System (ICS) with apochromatic (APO) color correction to minimize chromatic and spherical aberrations, essential for precise molecular biology workflows
• Thread Type: M27x0.75 for secure mounting
• Immersion: Dry (without immersion oil), enabling convenient sample handling while maintaining high optical performance
• Field of View: 25 mm, providing a broad observation area for bioprocessing research and fluorescence imaging
• Parfocal Length: 45.06 mm, compatible with standard microscope configurations
• Application Compatibility:
• Fluorescence microscopy: Excellent for molecular diagnostics and synthetic biology studies
• Brightfield: High-quality imaging for histology and cell culture analysis
• Differential Interference Contrast (DIC): Supported for enhanced contrast imaging
• Not suitable for phase contrast, darkfield, or reflected light applications

This objective undergoes stringent quality control and cleaning by certified technicians, including optical verification with fluorescence and brightfield samples, ensuring consistent image quality vital in biomanufacturing and gene editing research pipelines. The mechanical components are lubricated and tested for smooth operation when applicable.

Ideal for researchers requiring high-resolution, apochromatic corrected objectives in cell imaging, neuroimaging applications, and essential molecular biology experiments, this lens supports robust biotechnological and clinical diagnostic workflows.

The product includes warranty coverage, technical sales consultations, and professional packaging to guarantee safe delivery and reliable post-sale support — critical factors for laboratory instrument procurement and long-term bioprocessing projects.
