Description
Introduction
BM45MR Series Metallurgical Microscope is a feature-packed, economical metallurgical microscope with an upright design, and both transmitted and incident illumination. The episcopic illuminator includes removable polarizer and analyzer, as well as adjustable field and aperture diaphragms. The plan-achromatic optical system offers sharp, flat-field images with excellent color-correction. The Siedentopf head with dual diopters and eye-point eyepieces provides a comfortable and adjustable viewing platform. There is also a dedicated photo port for simultaneous viewing and imaging.
Change magnifications quickly using the objective turret without significant refocusing thanks to the parfocal design. Using the included 10X eyepieces and a combination of metallurgical and biological objective lenses, the magnification range spans from 40X to 500X with five unique settings. The lenses are achromatically corrected for improved resolution, and flat-field corrected to ensure edge-to-edge sharpness.
