Overview
Binocular Polarized Microscope 59XB uses a transmission illumination system, which is mainly used for the observation and identification of various transparent crystals, rocks, minerals and birefringent substances. It is one of the most commonly used professional experimental instruments in geology, mining and other departments and related universities. It can also be used for Spinning & weaving, chemical fiber industry, and unit inspection of Spinning & weaving fibers. The Microscope can be used by users for single polarized observation, orthogonal polarized observation, conic observation and microscopic photography. It is equipped with Accessories such as plaster input, mica 1/4 test piece, quartz wedge and moving ruler. It is a group of products with complete functions and good quality.
Features
1. Adopt a transmission lighting system, suitable for the observation and identification of transparent crystals, rocks, minerals, and birefringent substances.
2. Equipped with a skateboard-type binocular observation head, the pupil distance can be adjusted (55-75mm) for comfortable observation.
3. Adopt Kohler lighting system, Illuminant is 6V/20W halogen lamp, wide voltage (85-230V) input, adjustable luminance.
4. Configure Abbe condenser with variable light bar to improve imagery mass.
5. The polarizer can be 360 ° swirl/spin and can be moved out of the light path, and the polarizer can be used as 90 °/180 ° swirl/spin, which is convenient for switching between various polarized light Observation modes.
6. The stage can be swirled/spun 360 ° and has equal divisions, which is convenient for sample positioning and analysis.
7. Provide a variety of Accessories, such as plaster test piece, mica 1/4 test piece, quartz wedge and moving ruler, fully functional.
8. The total magnification covers 40X to 630X, meeting different observation requirements.
Principle
The binocular polarized microscope 59XB works based on the principle of polarized light. The ray of light emitted by its illumination system becomes polarized after passing through the polarizer, and is irradiated to the transparent sample placed on the rotating stage. When the sample has birefringence characteristics, it will change the vibration direction of the incidence polarized light. The changed ray of light then passes through the polarizer. By analyzing the changes of Light intensity, interference color, etc., the crystal structure and Optical inspection properties of the sample can be identified. Observation modes such as single polarized light, orthogonal polarized light and conical light can be realized through swirl/spin polarizer, polarizer and stage, and with various compensation test pieces.
Applications
Geology and mineral identification, teaching experiments in colleges and universities, Spinning & weaving fiber inspection, chemical fiber industry analysis
Standards
No specific compliance criteria were mentioned in the data.
Steps
1. Turn on the power, turn on the lighting system, and adjust the luminance to an appropriate level.
2. Place the sample to be tested on the stage and secure it using a moving ruler or tablet holder.
3. According to the observation requirements, choose the appropriate objective lens (e.g. 4X, 10X, 40X, 63X) through the swirl/spin converter.
4. Use a coarse fretting coaxial focusing handwheel to focus until the field of vision is clear.
5. Depending on the Observation mode (single polarized, orthogonal polarized or conical), swirl/spin or move in/out polarizers and detectors.
6. In orthogonal polarized or conical observation, the stage can be rotated 360 ° and used in conjunction with Accessories such as plaster, mica 1/4 test piece or quartz wedge for detailed analysis.
7. After the observation is completed, turn off the power, remove the sample, and turn the objective lens to the lower magnification position.
Notice
When moving or handling the Microscope, hold the base and mirror arm with both hands and handle them with care.
When switching objectives, be careful to avoid collisions between the objective and the stage or sample.
When adjusting the focal length, use the coarse focus knob first, and then use the fine-tuning after getting close to the focus to avoid damaging the lens or stage.
* The halogen lamp generates heat when it works, so avoid touching the lamp chamber for a long time. Make sure the instrument is powered off and chilled down before changing the bulb.
* Keep the Optical inspection parts clean, if there is dust, it should be handled gently with a special balloon or lens paper, and avoid directly touching the lens with your hands.
After use, it is recommended to cover the instrument with a dust cover.
Non-professionals should not disassemble the internal structure of the Microscope by themselves.
