The MAGUS Lum 400L fluorescence microscope can be used for two microscopy techniques: fluorescence in reflected light and bright field in transmitted light. When equipped with additional accessories, the microscope can be used to conduct research in polarized light and for phase contrast and dark field techniques. You can use the microscope for laboratory research and diagnostics in the fields of medicine, pharmacology, forensic science, biotechnology, veterinary medicine, etc.
Optics
The trinocular head is composed of two optical tubes for conducting observations and a trinocular tube for housing a digital camera (not included). To face long periods of observation in maximum comfort, it is possible to adjust the eyepiece tubes by rotating them 360° to adapt to the height of the observer. They are inclined by 30°.
The nosepiece with five objectives is oriented inwards, so that the user can see which objective is inserted in the optical path. It is equipped with infinity planachromatic objectives: three for the bright field technique and one for the fluorescence (fluorescent) technique. Once all objectives are installed on the nosepiece, one slot remains available. It is used to adjust the position of the illuminator for reflected light observations. You can also install an optional lens to achieve higher magnification.
Illumination
Reflected light: five 5W LEDs. Each LED falls into four bands specifications: blue (B), green (G), violet (V) and ultraviolet (UV). To choose the LED you need to rotate the ring. The advantage of LED lighting is that it quickly reaches maximum brightness and turns off quickly, making it easy to switch from brightfield to fluorescence and vice versa. The LEDs do not overheat, do not require a heat sink and have a lifespan of 50,000 hours before needing replacement. LED fluorescence is a safe and easy to maintain microscopy technique, therefore it is recommended for use in schools and universities.
The transmitted light is produced by a 3 W LED. The life cycle of LEDs is 50,000 hours. The lighting system also includes a capacitor. The condenser has an available slot for a dark field slider or a phase contrast slider. The slider makes it quick and easy to switch from one microscopy technique to another without having to change the condenser.
In transmitted and reflected light, Köhler illumination can be set. The study object is sharp and has no image artifacts. The edges do not darken and each objective reaches maximum resolution.
Stage and focusing mechanism
The microscope stage is equipped with a holder removable sample in order to perform manual scans of the same. The table does not have a positioning rack, therefore it requires less working space. You can install a black plate on the stage to eliminate any unwanted light from the transmitted light light source when observing in reflected light.
The coaxial fine (micrometer screw) and coarse (micrometer screw) focus knobs macrometric) are positioned on both sides at the base of the microscope. The coarse focus is equipped with a fixing knob and tension adjustment.
