8-Various observation methods, including phase contrast, Hoffman modulation phase contrast, and 3D emboss contrast, are available with transmitted illumination, allowing for clear, high-contrast imaging of living cells, microorganisms, tissue slides, and more.
9-LED Fluorescent Attachment is Optional:
(1)Inverted biological microscope BS-2094C makes fluorescent observation easier with an optional LED attachment.
The system uses a fly-eye lens and Kohler illumination to ensure a uniform, bright field of view, ideal for capturing high-definition images with remarkable detail. Unlike traditional mercury lamps, the LED light source has a longer service life, is more energy-efficient, and eliminates the issues of preheating, excessive heat, and cooling delays—offering a smoother, safer, and more cost-effective user experience.
(2) Inverted biological microscope BS-2094C is suitable for use with a wide variety of fluorescent dyes.
The LED fluorescent attachment includes three filter blocks, making it compatible with a broad spectrum of fluorescent stains. This allows for sharp, high-contrast fluorescence imaging, suitable for numerous research and diagnostic applications.
