Fluorescent LED Microscope, semi-APO, Trinocular YR06649

The YR06649 Semi-APO Trinocular LED Fluorescence Microscope is an advanced solution for laboratories requiring high-precision fluorescence observation, combining a Plan Infinity optical system, an integrated 5 W LED fluorescence unit, and a Seidentopf trinocular configuration that facilitates digital documentation and prolonged work with maximum comfort. Its design supports 1 or 2 fluorescence filters (B and G), making it a versatile tool for applications in cell biology, microbiology, histology, biomedical research, and university teaching. It is equipped with Infinity Plan objectives (4x, 10x, 40x, and 100x oil immersion) featuring an iris diaphragm, delivering sharp, flat images with excellent chromatic correction. In addition, it can be upgraded to semi-APO fluorescence objectives and a 100x water immersion objective, allowing performance to scale according to laboratory needs. The high-brightness 6 V / 30 W halogen illumination system, combined with a swing-out condenser NA 0.9/0.13, ensures optimal contrast across multiple observation techniques. In the market, this type of trinocular fluorescence microscope is positioned within a competitive price range compared to premium brands, offering an excellent cost-to-performance ratio for institutions seeking reliable fluorescence capabilities without oversizing their investment. Thanks to its modular configuration and professional optics, the YR06649 is a solid choice for both growing laboratories and established research centers.
