Product Description

 

The Labmart Cresta ZS 50i-MET Metallurgical Microscope is an inverted microscope designed for high-resolution examination of opaque materials using reflected illumination. It features an infinite optical system, binocular Siedentopf head, coaxial X-Y mechanical stage, halogen reflected illumination and a 5-position filter unit for metallography, materials research and industrial quality control.

Product Overview

The Cresta ZS 50i-MET is an inverted metallurgical microscope designed for examining specimens that do not transmit light, including metals, alloys, ceramics, minerals and other solid materials.

Its infinite optical system is designed for flat, detailed imaging of specimen surfaces. The inverted configuration facilitates positioning of suitable large, heavy or irregularly shaped samples on the mechanical stage.

A 6V/30W halogen reflected-light system provides illumination of the specimen surface. The optical path incorporates field and aperture diaphragms for Köhler illumination, while the five-position filter unit provides blue, green, amber, grey and empty filter positions for contrast adjustment.

The microscope incorporates a low-positioned mechanical stage with coaxial X-Y controls, allowing systematic movement across a specimen surface. Coaxial coarse and fine focusing provides controlled focusing, with fine focusing specified at 0.002 mm.

Key Features and Benefits

  • Inverted Metallurgical Configuration: Suitable for examination of opaque specimens and larger or irregular samples.
  • Infinite Optical System: Designed for flat-field, high-resolution observation.
  • Reflected Halogen Illumination: 6V/30W illumination provides light directed onto the specimen surface.
  • Köhler Illumination Controls: Field and aperture diaphragms support controlled illumination of the specimen.
  • Five-Position Filter Unit: Blue, green, amber, grey and empty positions allow contrast adjustment.
  • Quadruple Ball-Bearing Nosepiece: Provides smooth objective positioning.
  • Coaxial X-Y Mechanical Stage: Facilitates systematic movement across the specimen surface.
  • Precision Coaxial Focusing: Coarse and fine focusing, with 0.002 mm fine division, supports detailed microstructural examination.
  • Siedentopf Binocular Head: Provides comfortable binocular observation with adjustable interpupillary distance and diopter correction.
  • Chemical-Resistant Construction: Cast-iron body with stipple-grey chemical-resistant finish.
