High-efficiency 66mm annular ringlight with continuous fiber optic illumination, shadow-free for microscopy.
The SCHOTT 157.420 KL Series Annular Ringlight is a precision-engineered fiber optic illumination accessory designed to provide uniform, shadow-free light essential for high-resolution microscopy applications. Featuring a continuous ring of illumination fiber integrated within a rugged, black anodized aluminum housing, this 66mm diameter ringlight mounts directly onto microscope objectives via a thumb screw, supporting standard objectives sized 58mm or 66mm.
Key technical specifications include:
This advanced annular ringlight is widely utilized in biotechnology laboratories and research facilities focusing on bioprocessing, gene editing workflows, and biopharmaceutical production pipelines, where precise and even illumination dramatically impacts image quality and data reproducibility. The device’s modular design supports seamless integration into microscopy systems used for neuroscience, cell imaging, and clinical diagnostics, making it an essential tool for molecular biology researchers requiring consistent illumination during complex imaging protocols.
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.
Yes. Every verified supplier states which service partners cover the instrument, and we list that 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.
