Zeiss Plan-APOCHROMAT 20x/0.60 Ph2 Microscope Objective RMS Thread

The Zeiss Plan-APOCHROMAT 20x/0.60 Ph2 (model 44 06 41) is a high-performance microscope objective designed for phase contrast microscopy and advanced biological imaging applications. Featuring a 20x magnification and a numerical aperture (NA) of 0.60, this dry immersion objective offers excellent resolution and contrast for detailed visualization of transparent specimens. The RMS thread ensures compatibility with standard microscope nosepieces.

Key technical features include:

• Plan-Apochromat optical correction for minimized chromatic and spherical aberrations, enabling sharp, flat-field imaging essential in cell imaging and live-cell phase contrast microscopy.
• Phase ring type 2 (Ph2) optimized for phase contrast applications, improving contrast in transparent biological samples without staining, critical in neuroscience, molecular diagnostics, and biotechnology research such as synthetic biology workflows.
• The objective is dry immersion, facilitating ease of use in routine laboratory environments dealing with bioprocessing and biomedical engineering.
• Thoroughly inspected, cleaned, and lubricated (if applicable) by expert technicians to ensure mechanical reliability and optical performance.

This objective is widely adopted in fluorescence analysis and clinical diagnostics laboratories, playing an important role in biopharmaceutical production pipelines and molecular cloning workflows that demand precise optical components for microscopy-based analysis. Compatible with various Zeiss microscopes equipped with RMS threading, it is critical equipment for researchers focusing on high-fidelity phase contrast imaging in biotechnology and life science research.
