Overview
69XC trinocular polarized microscope is a professional experimental instrument using a transmission illumination system, mainly used for the observation and identification of various transparent crystals, rocks, minerals and birefringent substances. It is a commonly used equipment in geology, mining, metallurgy and other departments and related institutions of higher learning, and can also be used for fiber inspection in Spinning & weaving and chemical fiber industries. The product is fully functional and supports single-polarized observation, orthogonal polarized observation, conic observation and microphotography, and is equipped with Accessories such as plaster lambda film, mica 1/4 lambda test film, quartz wedge and moving ruler.
Features
1. Adopt a transmission lighting system, suitable for the observation and identification of transparent crystals, rocks, minerals, and birefringent substances.
2. Provide a variety of Observation modes such as single polarization, orthogonal polarization, cone light observation and microphotography.
3. Equipped with plaster lambda, mica 1/4 lambda test, quartz wedge, moving ruler and other professional Accessories, complete functions.
4. The observation head can be swirled/spun 360 °, providing two options: skateboard binocular barrel (45 ° tilt) and twisted chain binocular barrel (30 ° tilt).
5. Adopt coarse fretting coaxial focusing system, with a fretting grid value of 0.002mm, and with limited position and locking device.
6. Equipped with swirl/spin round table (φ 160mm, 360 ° Division, etc.) and load round plate (outer diameter φ 80mm, inner hole φ 24mm).
7. Adopt 1.30N.A. Abbe condenser, with variable light bar and color filter, and equipped with 0 °~ 90 ° rotating polarizer.
8. Illuminant 12V/30VA halogen tungsten lamp, adjustable luminance.
Principle
This Polarized Microscope works based on the principle of polarized light. The light emitted by the Illuminant becomes polarized after passing through the polarizing device (configured on the condenser) and shines on the sample. Analysis and interference occur when the ray of light passes through the sample with birefringence characteristics (e.g. crystals, minerals). Optical inspection characteristics of the sample in different polarization directions can be analyzed through the swirl/spin polarizer (0 °~ 90 ° rotating type), so as to realize the identification of material composition, structure, orientation, etc. The configured complementary color device (e.g. plaster lambda sheet, mica 1/4 lambda sheet, quartz wedge) can be used to accurately determine the phase difference and optical path difference of the sample.
Applications
Geology, minerals, metallurgy, colleges and universities, Spinning & weaving, chemical fiber

Steps
1. Turn on the power and adjust the Illuminant luminance.
2. Place the sample on the stage (round plate or moving ruler).
3. According to the observation requirements (single polarized, orthogonal polarized or conical), swirl/spin polarizer and polarizer to the appropriate position.
4. Use the coarse fretting coaxial focusing knob to focus the sample.
5. For accurate measurement or complementary color observation, the corresponding complementary color device (plaster lambda, mica 1/4 lambda or quartz wedge) can be inserted.
6. Move and position the sample by swirl/spin table (360 ° swirl/spin) or moving ruler.
7. Observe through the eyepiece, or connect the three-eyepiece barrel for microphotography.
Notice
Please ensure that the instrument is placed on a stable surface before use.
When operating the focusing system, avoid using rapid or excessive force to prevent damage to the sample or objective lens.
* Accessories such as changing the objective lens or inserting the complementary color should be done gently.
* Keep Optical inspection components (such as eyepieces, objective lenses, condensers) clean and avoid touching the lens directly with your hands.
* Illuminant (tungsten halogen lamp) generates heat when working, do not touch the lamp room for a long time.
* After use, please turn off the power and turn the luminance to the lowest level.
When not in use for a long time, it is recommended to cover the instrument with a dust cover.
