The microscope is designed for studying specimens using the fluorescence microscopy technique in reflected light and brightfield technique in transmitted light. The additional equipment allows for darkfield polarization and phase contrast microscopy. Fluorescence microscopy is based on the ability of some substances to glow when exposed to the light of a certain part of the spectrum. The specimens are exposed to invisible short-wave ultraviolet light or violet blue and green light. The wavelength of the emitted light will be longer than the wavelength of the excitation light. The specimen glows blue cyan green-yellow or red light respectively. Some specimens glow by themselves while others glow after treatment with fluorochromes. The fluorescent microscope is used to study pathogens of tuberculosis chlamydia rabies herpes and other diseases. The microscope can also be used for DNA and chromosome analysis bone marrow and blood smears forensic and pharmacological examination veterinary control studies and sanitary and epidemiological inspection.

Microscope head

Trinocular head with infinity-corrected optics. Eyepiece tubes can rotate 360°. The user can adjust eye relief on the eyepiece to fit their height. The digital camera is mounted in the trinocular tube.

Revolving nosepiece

Five objectives. A free slot is used for centering the reflected light source. An additional objective can also be installed in the free slot in order to achieve extra magnification. The revolving nosepiece with objectives is oriented toward the interior – the user can see the objective inserted into the optical path and the space above the stage is free.

Objectives

Infinity plan achromatic objectives and infinity plan fluorite objectives. Standard configuration includes 4x 10x and 100x objectives for brightfield microscopy and a 40x objective for fluorescence microscopy.

Focusing mechanism

Coaxial coarse and fine focusing knobs are located at the base of the microscope on both sides. The user can place their hands on the table and take a relaxed pose while observing. The focusing adjustment is smooth and effortless. On the right there is a coarse focusing lock knob for quick adjustments after changing the specimen. On the left there is a coarse tension adjustment ring for further adjustment.

Stage

The stage does not have an X-axis positioning rack which ensures its ergonomic operation. The mechanical stage with a belt-driven mechanism allows for the smooth movement of the object. The slide holder is fixed with two screws and can be removed for easy operation. For reflected light observations a black stage plate should be placed on the stage to remove stray light.

Reflected light illuminator

The fluorescence excitation light source: 5W LEDs of four wavebands: blue (B) green (G) violet (V) and ultraviolet (UV). The LEDs can be changed by rotating the ring. The LEDs will instantaneously reach full brightness won’t heat up during prolonged use and will turn off quickly when needed. It makes it easy to switch from the brightfield technique to fluorescence and back again. The lifetime of the LEDs is 50 000 hours. It is recommended to choose an LED-based fluorescence microscope for educational purposes as the safest and low-maintenance option.

Köhler illumination in reflected and transmitted light

Setting up the Köhler illumination enhances the image quality of a specimen. With such illumination you can achieve maximum resolution on each objective and uniform illumination of the field of view with no darkening at the edges. The object of study is in sharp focus and the image artifacts are removed.

Condenser

The condenser has a slot for a darkfield slider or a phase contrast slider. The usage of the slider saves time when switching between microscopy techniques in transmitted light.

Transmitted light source

The transmitted light illuminator has a 3W LED. The color temperature does not change when adjusting the brightness. The LED has a lifespan of 50 000 hours.

Accessories

There is a line of accessories designed for the microscope. Optional objectives provide additional magnification. The optional 10x/0.35 fluorite objective is used for capturing an image of a specimen with a resolution of 0.5μm over a large field of view. Eyepieces that extend the magnification range of the microscope. Optional eyepieces help you maximize the potential of the objective you use most often. A phase contrast device a darkfield condenser and a polarization device offer more microscopy techniques so that you can study the specimens that are invisible in brightfield or fluorescent light. A digital camera that outputs the microscope image on a monitor and stores files along with software that takes real-time measurements of specimens. A calibration slide for measuring objects that can be combined with an eyepiece with a scale or the camera software.
