Product description

Infinity-corrected Zeiss 2.5x polarization microscope objective with 0.075 NA and RMS mount.

The Zeiss EC Plan-NeoFluar 2.5x / 0.075 polarization microscope objective, article number 420323-9901, is designed for infinity-corrected Zeiss microscopy systems, particularly polarization microscopes. Its low 2.5x magnification provides a broad overview of larger specimen areas while maintaining detailed image observation.

The objective is suitable for polarization microscopy, geology, materials research, and bioscience applications involving crystalline or anisotropic samples. Stress-free optics support polarization-optical examinations, while the Plan-NeoFluar correction class provides improved image-field performance and color correction.

Technical specifications:

  • Magnification: 2.5x
  • Numerical aperture: 0.075
  • Optical correction: EC Plan-NeoFluar, plan-corrected design
  • Optical configuration: Infinity-corrected
  • Tube length: Infinity (∞/0)
  • Cover glass correction: Without cover glass (0)
  • Mounting thread: RMS, 4/5 inch × 1/36 inch
  • Dimensions: approximately 45 mm length × 28 mm diameter
  • Weight: approximately 95 g
  • Application: Polarization microscopy, overview imaging, geological and materials analysis
  • Compatibility: Zeiss microscopes with infinity optical systems, especially polarization microscopes

The listed objective is in very good condition, with clear optics, no reported scratches or fungal growth, and smoothly operating mechanics.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
