Nikon Nikon Cfi Super Fluor 10X Na 05 Wd 11Mm Mrf00101 — High-Performance Objective Lens for Microscopy (Nikon)

How Much Does Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 Cost in 2026?

The Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 is currently priced at $5,329 for a used, B-grade unit. This is a typical price for a refurbished objective lens in this condition, and represents a 40–60% discount compared to the new price, which can exceed $10,000. Refurbished units are commonly available through vendors like Ferrotec and Axus Technology, both of which have a strong track record with Nikon optics.

Used units in “A” condition (i.e., fully tested, with full warranty) can range up to $6,500, but these are rare and often come with extended lead times. The savings are significant, but the risk of failure is real—especially if the unit has more than 10,000 hours of use. A failed lens can result in $2,000–$5,000 in downtime and replacement costs, depending on the system it’s used in. Always verify the condition and usage history before purchase.

Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 Specifications and Compatible Tools

The Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 is a 10X objective lens with a numerical aperture (NA) of 0.5 and a working distance (WD) of 1.1mm. It is designed for high-resolution imaging in fluorescence and brightfield microscopy. The lens is typically used in systems such as the Nikon Eclipse C1 and C2 series microscopes, which were commonly deployed in the 2000s.

These lenses are known for their durability, but they are not rated for more than 10,000 RF-hours of continuous use. If used beyond this, the lens may exhibit chromatic aberration or reduced clarity, which can impact inspection accuracy. Incompatibility is a concern with newer Nikon systems like the Ti2 or A1R, which use different mounting standards. Specifically, the MRF00101 is not compatible with the Nikon CFI60 standard used in post-2010 systems. Using an incompatible lens can void warranties and lead to system misalignment, costing $1,500–$3,000 in repairs.

What to Check Before Buying a Used Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 in 2026

1. Verify Usage Hours: Look for a unit with less than 8,000 RF-hours. Units with more than 10,000 hours are at high risk of optical degradation.
2. Check for Lens Coating Damage: Use a magnifying loupe or a spectrophotometer to inspect the lens coating. Any visible scratches or haze can reduce image quality.
3. Test for Chromatic Aberration: Use a standard test slide with a known pattern. If the image is out of focus or shows color fringing, reject the unit.
4. Confirm Mounting Compatibility: Ensure the lens uses the CFI standard. Do not accept units with CFI60 mounts, as they are incompatible with most legacy systems.
5. Production Year Reference: Units made before 2008 are more likely to have lower-quality coatings and are not recommended for high-precision applications.

A poorly tested lens can lead to system downtime and inaccurate data, costing $2,500–$4,000 in lost productivity and rework. Always request a full inspection report and warranty from the seller.

FAQ

Q: Can I use the Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 in a Nikon Ti2 microscope?
A: No. The Ti2 uses the CFI60 standard, while the MRF00101 uses the older CFI standard. Attempting to use it in a CFI60 system can cause mechanical misalignment and damage the lens, costing up to $3,000 in repairs.

Q: Should I buy a used Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 with more than 10,000 hours of use?
A: No. Units with over 10,000 hours are at high risk of optical failure. A failed lens can cost $2,000–$5,000 in downtime and replacement, depending on the system.

Q: How long does a Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 typically last?
A: These lenses typically last 8,000–10,000 RF-hours before showing signs of wear. Regular cleaning and proper storage can extend their life by 10–15%.

Q: What is the difference between the CFI and CFI60 standards?
A: The CFI standard is used in pre-2010 Nikon microscopes and has a 20mm tube length. The CFI60 standard is used in newer systems and has a 60mm tube length. The two are not interchangeable without an adapter, which can introduce optical errors.

Q: Is it worth buying a used Nikon CFI Super Fluor 10X Na 0.5 Wd 1.1mm MRF00101 instead of a new one?
A: Yes, if the unit is in A or B condition and has less than 8,000 hours of use. You can save 40–60% compared to a new lens, but only if the unit is properly tested and comes with a warranty.
