Fiber optic cannula with Ø1.25 mm ceramic ferrule, 105 µm core, 0.22 NA, 2 mm length, suited for fiber-optic light delivery.
The Thorlabs CFMLC21L02 is a precision fiber optic cannula designed for efficient light delivery in research applications such as neuroscience, optogenetics, and photonics. It features a ceramic ferrule with a diameter of Ø1.25 mm for robust and stable fiber coupling. The optical fiber core diameter is 105 µm with a numerical aperture (NA) of 0.22, enabling effective light transmission with controlled beam divergence suitable for precise excitation or sensing.
Key features include:
Widely used in biomedical engineering and biomanufacturing research, this fiber optic cannula is essential for precise fiber-optic light guidance and is popular among scientists working on molecular cloning workflows and biopharmaceutical production pipelines that require stable and reproducible optical interfacing.
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.
