Evident CKX41 Inverted Biological Microscope MF-LED Multi-Channel LED Fluorescence Attachment The MF-LED multi-channel fluorescence module is a dedicated, user-friendly upgrade solution designed specifically for the Evident CKX41 inverted biological microscope. Built with high-brightness color LEDs as the light source, it provides a cost-effective way to transform a standard infinity-corrected inverted biological microscope into a fully functional fluorescence imaging system without modifying the original optical path. The three-color three-channel design supports common fluorescence bands including UV (V), Blue (B), Green (G), Yellow (Y), and Red (R), meeting diverse basic fluorescence observation needs such as DAPI, FITC, and TRITC applications. Equipped with a digital display screen, it enables precise control of LED light intensity (0–100%) and independent memory for each channel, ensuring consistent brightness and reliable performance for quantitative experiments. The expanded light field of view ensures excellent compatibility with the Evident CKX41 and other major brand microscopes. Supporting instant on/off operation with no preheating required, this LED-based module offers a long lifespan, low heat generation, and low maintenance costs while fully retaining the microscope’s original brightfield observation function.
