Product Specification Sheet
Binocular Polarising Microscope (MT-271 Series)
Model Number: MTMM-12
The Binocular Polarising Microscope (MT-271 Series) is designed for detailed examination of transparent and anisotropic materials under polarized light. Manufactured by Micro Technologies, it combines strain-free plan achromatic optics, a rotatable mechanical stage, polarizer, analyzer, retardation plates, and controlled illumination for geological, mineralogical, material science, and industrial research applications.
Product Specification
The Binocular Polarising Microscope (MT-271 Series) is a precision optical instrument developed for observing the structural, optical, and crystalline characteristics of materials under transmitted polarized light. Manufactured by Micro Technologies, it is suitable for geology laboratories, mineralogy departments, material science facilities, petrographic analysis, industrial inspection, research institutes, and advanced microscopy applications.
Its built-in illumination system and high-quality coated optics provide strong image contrast and clear specimen visibility. The optical system is designed with strain-free components to minimize unwanted optical interference while examining crystals, minerals, fibers, polymers, and other birefringent materials.
The microscope incorporates a polarizing attachment with an analyzer mounted on the stand for smooth insertion and removal from the optical path. A standard compensator slot accommodates a sensitive tint plate and a quarter-wave retardation plate, supporting advanced optical analysis and identification of material properties.
A rotatable polarizer provides full 360° adjustment, allowing the operator to control the direction of polarized light according to the specimen and examination method. The inclined observation head offers comfortable viewing, while the binocular body rotates through 360° for convenient use from different working positions.
The quadruple revolving nosepiece is mounted on precision ball bearings for smooth objective changes and accurate optical alignment. Anti-fungal parafocal achromatic objectives provide dependable clarity across multiple magnifications, while the supplied wide-field eyepieces include cross-line and graticule options for measurement and alignment work.
The mechanical stage incorporates a circular rotating plate with continuous 360° rotation, enabling accurate angular examination of specimens. The Abbe condenser with N.A. 1.25, rack-and-pinion movement, iris diaphragm, and swing-out filter holder provides controlled illumination and improved contrast.
A separated coarse and fine focusing mechanism with a four-stage gear reduction system supports smooth, precise adjustment. Illumination is provided through a base-mounted light source with variable intensity control, an ON/OFF switch, and a plano-concave reflector for daylight observation when required.
Each MT-271 Series Polarising Microscope from Micro Technologies is inspected for optical alignment, mechanical accuracy, illumination performance, and dependable operation before supply.
