The MAGUS Lum 400L Fluorescence Microscope can be used for two microscopy techniques: fluorescence in reflected light and brightfield in transmitted light. When equipped with additional accessories, you can use the microscope to conduct research in polarized light as well as use darkfield and phase contrast techniques. The microscope can be used for research and laboratory diagnostics in the fields of medicine, pharmacology, forensics, biotechnology, veterinary medicine, etc.


The trinocular head includes two eyepiece tubes for observations and a trinocular tube for mounting a digital camera (not included). For comfortable longer observations, the eyepiece tubes can be adjusted to match the height of the observer, as they rotate 360°. They are 30° inclined.

The 5 objectives revolving nosepiece is oriented toward the interior – the user can see the objective inserted into the optical path. It comes with four infinity plan achromatic objectives: three for brightfield and one for fluorescence technique (fluo). One slot is left free when all objectives are installed in the revolving nosepiece. It is used for adjusting the position of the reflected light illuminator. You can also install an optional objective to get extra magnification.


The reflected light – four 5W LEDs. Each LED has in a specific waveband: blue (B), green (G), violet (V), and ultraviolet (UV). To choose the working LED, you have to rotate the ring. The advantage of LED illumination is that LEDs get bright quickly and turn off quickly, making it easy to switch from brightfield to fluorescence and back again. LEDs do not heat up, they do not need a heat sink, and they have a lifetime of 50,000 hours without replacement. LED-based fluorescence is an easy to maintain and safe microscopy technique and, therefore, it is recommended for use at schools and universities.

The transmitted light is produced by a 3W LED. It also has a lifespan of 50,000 hours. The illumination system also includes a condenser. The condenser has a slot for a darkfield slider or a phase contrast slider. A slider is an easy and quick way to change the microscopy technique without changing the condenser.

For both transmitted and reflected light, you can set up Köhler illumination. The object of study is in sharp focus, and the image artifacts are removed. There is no darkening at the edges and the resolution limit can be reached at each objective.

Stage and focusing mechanism

The microscope stage is equipped with a removable specimen holder, which can be removed for manual scanning. The table does not have a positioning rack. Therefore, it requires less space for work. A black stage plate can be installed on the stage to eliminate stray light from the transmitted light source when observing in reflected light.

Coaxial coarse and fine focusing knobs are located at the base of the microscope on both sides. Coarse focusing has a lock knob and tension adjustment.


The MAGUS Lum 400L microscope has a wide range of compatible accessories that can be used to expand its capabilities. It includes eyepieces, objectives, darkfield, polarized light and phase contrast devices as well as digital cameras and calibration slides.
