Description
Digital camera
The MAGUS CLM50 digital camera is designed for use in fluorescence and darkfield microscopy techniques.
The camera is equipped with a 1.7MP sensor producing a realistic image in 1600x1100px.
Video is recorded at 33fps at maximum resolution. Videos are smooth, with soft and subtle transitions between frames. The movement of the sample is displayed in real time with no delays. The camera provides convenient work with moving objects and is suitable for conducting demonstrations in a classroom.
The camera is equipped with a USB 3.0 interface. The data transfer rate is 10 times faster than that of USB 2.0 cameras. The high-speed camera is recommended for professional laboratories, research, or university training.
Microscope head
Trinocular, with infinity-corrected optics. The eyepiece tubes are 360° rotatable. The user can adjust the eyepiece height to suit their individual stature. The digital camera is mounted in the trinocular tube. The beam splitting ratio is fixed at 50/50.
The vertical tube provides 0.55x magnification. When paired with the included 1x adapter, the final magnification at the camera is 0.55x. When calculating the field of view and on-screen magnification for each objective, use a total factor of 0.55x.
The basic configuration includes 10x/22mm eyepieces with diopter adjustment and high eyepoint for working with glasses. Flat rubber eyecups protect eyeglasses from scratches.
Revolving nosepiece and objectives
The coded revolver for five 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. An additional objective can also be installed in the free slot in order to achieve extra magnification. The parfocal distance is 60mm.
The 40x objective with its extended working distance of 1.5mm provides additional protection for the front lens against immersion oil contact when rotating the nosepiece.
Above the revolver, there is a slot with a plug for the analyzer.
Maintaining a comfortable brightness level in transmitted light when changing magnifications
The objectives of different magnifications transmit light with different levels of intensity, and so each time you change objectives, the brightness of the light must be adjusted. Switching from a higher to a lower magnification objective causes eye fatigue, as the image brightness in the eyepieces increases sharply. The MAGUS Lum D460L, which is equipped with intelligent brightness control, solves this problem. The microscope remembers the brightness for each objective that the user has selected and automatically sets this brightness when turning the nosepiece. Intelligent control reduces the time required to adjust brightness. MAGUS Lum D460L increases user comfort and saves you time even when your work requires frequent magnification changes.
Focusing mechanism
Coaxial coarse & fine focusing knobs.
The coarse focusing knob is located on the left side. Fine focusing knobs are located on both sides, the right knob having special finger indentations.
The ring on the left side adjusts the tension of the coarse focusing travel. The user adjusts the comfortable tension for work.
Stage
The stage has no X-axis rack and pinion, which improves ergonomics. The belt-driven mechanism allows for smooth movement of the specimen. The specimen holder is secured with two screws and can be easily removed during manual scanning.
The long stage control handle ensures user comfort: The hand rests on the table with no strain.
Motorized fluorescence attachment
There is a 4-position rotating turret inside the attachment with three broadband fluorescence filters of different wavelengths: blue (В), green (G), and ultraviolet (UV). The required filter is introduced into the optical path by clicking the button. One button on the attachment rotates the turret to the next filter clockwise, and the other one rotates the turret counterclockwise. One position of the turret corresponds to brightfield observations in transmitted light.
The excitation light sources are LEDs. The LEDs instantly reach the brightness that is set by the user. They do not heat up during prolonged use and can switch off quickly, if necessary. This makes it easy to switch from the brightfield technique to fluorescence and back again. The brightness of the LEDs is controlled by two additional buttons that are located in the same work area as the turret switching buttons. The LED lifetime is 50,000 hours.
It is recommended to choose LED-based fluorescence for higher education as it is the safest option and requires minimal maintenance.
Köhler illumination in transmitted light
Properly setting up Köhler illumination enhances the image quality of a specimen. With such illumination, you achieve maximum resolution for each objective and an evenly illuminated 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 is height-adjustable and can be centered. Mounting type: dovetail.
The condenser ring adjusts the iris aperture diaphragm. The condenser body has a marking for the magnification of the objectives, and the ring has an indicator marker. To achieve contrast on each objective, it is recommended to rotate the ring so that the index marker matches the magnification marking of the objective being used.
The condenser has a slot with a plug for a darkfield slider or a phase contrast slider. The installation of a slider saves time when changing the observation method.
Transmitted light source
The transmitted light illuminator uses a 3W LED. The color temperature does not change when you adjust the brightness. The LED lifetime is 50,000 hours.
Status LCD screen
The LCD screen on the base of the microscope displays the objective magnification, brightness and color temperature of the light source, and operating mode (“sleep” and “eco”).
Using the screen and two knobs, the microscope user adjusts the brightness, locks the brightness adjustment, and sets the sleep mode and auto-off timer.
Ergonomic design
Physical discomfort causes fatigue and reduces productivity. The ergonomic design of the microscope plays an important role in everyday scientific research.
MAGUS Lum D460L provides user comfort during operation.
By rotating the eyepiece tubes, the user can adjust the viewing height to prevent back and neck strain.
Focusing knobs are located at the bottom of the body. The user does not need to strain their hands. Thanks to the smooth movement of the mechanism, the user can effortlessly focus on the object.
The microscope is operated with minimal hand movement, since the long stage control handle and fine focusing knob are located in the same working area.
The microscope is equipped with a special carrying handle.
The design for the hidden placement of the power cord improves the workplace esthetic and safety of carrying the microscope as well as simplifies storage of the device.
Accessories
There is a line of accessories designed specifically for this microscope.
Optional objectives provide additional magnification.
Eyepieces extend the magnification range of the microscope. Optional eyepieces help you maximize the potential of the objective that you use most often.
The phase contrast device, darkfield slider, and polarizer/analyzer set offer more contrast techniques so that you can study specimens that are invisible in brightfield.
A calibration slide is used to measure objects and can be combined with the eyepiece with a scale or with the camera software.
