Description

Fluorescence microscope MAGUS Lum 400 is designed for diagnostics and research by methods of fluorescence (reflected light) and brightfield (transmitted light) microscopy. Darkfield, phase contrast, and polarization techniques can be used with optional equipment. Areas of application of fluorescence microscope: DNA analysis, study of pathogens, sanitary and epidemiological surveillance, forensic examination, etc.

Optics

This is a trinocular microscope: The binocular head is 30° inclined and the digital camera (not included) is installed in the trinocular tube. As the eyepiece tubes are 360° rotatable, it is easy to adjust them to fit the height of the user.

Five objectives can be installed in the revolving nosepiece. Four infinity plan achromatic objectives are included. One of them, a fluo objective with a 40x magnification, is designed for fluorescence observations. 4x, 10x, and 100x objectives are used for the brightfield microscopy technique. An additional objective can be mounted in the free slot of the revolving nosepiece to achieve extra magnification within the magnification range of the microscope.

The revolving nosepiece with objectives is oriented toward the interior – the user can see the objective inserted into the optical path.

Illumination

The reflected light source is a 100W mercury lamp. It is placed inside the lamphouse, which provides efficient heat dissipation: The lamp does not overheat even during long hours of operation. The lamp can be centered along three axes to provide the optimal illumination of the working area. If you need to replace it, it will be fairly easy to remove and install the bulb. The mercury lamp is suitable for fluorescent dyes because it has discrete peaks. The reflected light illuminator contains four excitation filters: ultraviolet (UV), violet (V), blue (B), and green (G).

Transmitted light source: 30W halogen bulb. It is bright enough to work with any objectives of any magnification. Thanks to the color temperature of the illumination, even long observations will not strain the eyes. The illumination system also includes a condenser. It has a slot for a slider (phase contrast or darkfield).

In transmitted and reflected light, you can set up the Köhler illumination method. When the illumination is set up in this way, there is no darkening at the edges, the sample is clearly visible, and the image artifacts are removed.

Stage and focusing mechanism

The microscope is equipped with an ergonomically designed stage without a positioning rack. When observing in reflected light, a black stage plate is placed on the stage to remove stray light. The specimen holder is removable and can be taken out, if necessary, by loosening two screws. The focusing knobs are coaxial and located on each side of the microscope. Coarse focusing has a lock knob and tension adjustment and fine focusing is used for focus adjustment.

Accessories

The MAGUS Lum 400 microscope can be equipped with additional accessories: digital camera, phase contrast device, polarization device, darkfield condenser, eyepieces and objectives, darkfield and phase contrast sliders. For measuring objects, the configuration can be supplemented with a calibration slide.
