MAGUS Lum 450L Fluorescence Microscope

The MAGUS Lum 450L microscope can be used to conduct research in brightfield and fluorescent light. With additional components, research in the darkfield method, phase contrast, or polarized light can also be conducted. During fluorescence observations, the MAGUS Lum 450L illuminates the sample in blue or green so that the objects produce green-yellow or red light, respectively. Fluorescence microscopes are used in medical examinations, forensic or pharmacological studies as well as veterinary and sanitary control. This model is equipped with a smart illumination system that adjusts the light intensity to the characteristics of the objectives, and an LCD screen on which you can control the operating parameters.

The microscope is equipped with a trinocular head: two eyepiece tubes, and the third one is for a digital camera. Eyepiece tubes are designed for infinity-corrected optics. The user can adjust their height by twisting the tubes 360°. Users with visual impairments have no restrictions in working with this microscope: The model comes with basic 10x/22mm eyepieces with diopter adjustment rings, and the exit pupil on the eyepieces is placed at a sufficient distance to allow working with glasses. The glass lenses and eyepieces are protected by flat rubber eyecups. When connecting a camera, the light beam in the microscope is split 50/50.

The revolving nosepiece has 5 slots for installing objectives. The parfocal distance is 60mm. The revolver is directed away from the observer, which leaves free space above the object stage for manipulation. The microscope set includes 4 objectives from 4 to 10x. You can install an additional objective in the free slot to expand the magnification range. The special feature of the revolver is its part of the “smart” lighting system. The user adjusts the light intensity to the magnification of each objective once, and then when turning the nosepiece, the light is set to the desired intensity automatically. Thanks to this, there are no sharp changes in the level of illumination in the eyepieces, the user’s eyes get less tired, and there is no need to waste time constantly adjusting the brightness of the light.

The object stage has an ergonomic design: The specimen is moved using a belt drive mechanism, there is no positioning rack, and the stage is controlled with a long handle. All the while, the user can keep their hands on the table without strain. The stage is equipped with a specimen holder secured with two screws and can be easily removed.

Focusing is performed using coaxial knobs on the stand: On the left, there is a coarse focusing knob, and fine adjustment is made by the knobs on the right and left sides. Another handle is used to lock coarse focusing. The travel tension is adjusted using a ring.

Lighting in the microscope is provided by 3W LEDs: a transmitted light illuminator works for brightfield studies, and a reflected light illuminator is used for fluorescence studies. To create a fluorescent glow, the set contains two filters, blue and green. They change when you turn the switch on the fluorescent attachment left or right. If the switch is centered, the microscope is ready for work in the brightfield method. The LEDs are designed for 50,000 hours of operation. They do not take time to reach the required intensity, do not change temperature, and turn off immediately.

The microscope allows you to adjust Köhler illumination, which is used for various research methods. It forms a high-quality image without traces of artifacts, the sample and the entire field of view are illuminated with even light without darkening at the edges.

The adjustable iris diaphragm condenser is height adjustable and centered. The connection to the microscope is made using a dovetail mount. For the ease of adjustment, there are marks on the body of the condenser corresponding to the magnification indicators of the objectives, and on its ring, there is a pointer. To achieve a contrast image, set the mark to the desired magnification. The condenser has a slot for installing darkfield or phase contrast sliders. When working using other methods, the slot is closed with a plug.

All of the selected parameters – the working objective magnification, lighting settings, and the current operating mode – can be monitored on the built-in LCD screen. By controlling two knobs, the user can set the sleep mode or set the timer to turn off, adjust the brightness or set it to lock.

The design of the microscope is aimed at maximum user convenience. In addition to the features already described, it has a carrying handle, and the power cord is hidden from view, which is not only esthetically pleasing but also safe.

The microscope can be supplemented with various accessories to expand its functionality: Eyepieces will add magnification, and optional components will allow you to conduct research using other methods. A calibration slide, in combination with eyepieces with a scale or with a digital camera, will help you measure an object.
