Product description

Infinity-corrected Zeiss polarization objective with 2.5x magnification and 0.075 NA for overview imaging.

The Zeiss EC Plan-NEOFLUAR 2.5x / 0.075 Polarization Microscope Objective 420323-9901 is an infinity-corrected objective designed for polarization microscopy. It provides a broad field of view for overview imaging while maintaining useful detail resolution across geological, materials science, and biological specimens.

  • Magnification: 2.5x
  • Numerical aperture: 0.075
  • Optical correction: Plan-NEOFLUAR, plan-achromatic with improved field flattening
  • Application: Polarization microscopy, overview imaging, geological samples, and materials research
  • Polarization optics: Stress-free mounted lenses for polarization applications
  • Tube length: Infinity (∞/0)
  • Cover-glass correction: No cover glass (0)
  • Thread/mount: RMS, DIN 4/5" × 1/36"
  • Dimensions: Approximately 45 mm length × 28 mm diameter
  • Weight: Approximately 95 g
  • Compatibility: Zeiss microscopes with infinity optical systems, particularly polarization microscopes

The low 2.5x magnification is suited to surveying larger sample areas, while the 0.075 NA supports effective contrast and light transmission for crystalline and anisotropic materials. Stress-free construction makes this Zeiss microscope objective suitable for polarized-light imaging in geology, materials characterization, and related laboratory research.

The objective is described as being in very good condition, with clear optics, unobstructed viewing, and no scratches or fungus. The mechanical operation is smooth.

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.
