Nikon CF Plan 20x microscope objective with 0.40 NA, 11.0 mm extra long working distance for metallurgical applications.
The Nikon CF Plan 20x Epi ELWD microscope objective is designed for high-performance metallurgical and industrial microscopy applications requiring an *extra long working distance* (WD 11.0 mm). Featuring a numerical aperture (NA) of 0.40 and infinite optical correction (∞/0), it supports high-resolution imaging with minimal aberrations. The objective uses a standard RMS thread for compatibility with most microscope stands. Its *epi-illumination* design makes it suitable for reflective sample analysis, essential in biotechnology workflows involving material characterization and biomanufacturing quality control. The lens barrel exhibits cosmetic wear and the front lens has fine scratches, which should be considered for fringe imaging quality. This objective is widely used in industrial microscopy, materials science, and synthetic biology research requiring precise surface topology observation.
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.
With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.
Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.
Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.
Two to six weeks, depending on refurbishment scope and whether calibration is included.
We ship to 38 countries. Crating and customs handling are quoted with the instrument.
Tell us what you need and a scientist finds it for you, usually within the hour.
