The Reichert-Jung Polyvar Met is a research-grade metallurgical microscope built on infinity-corrected optics with a modular design for materials science and industrial analysis. It delivers magnifications from 16x to 2000x through interchangeable Plan achromat and Plan fluorite objectives, paired with 10x widefield eyepieces offering a 51° viewing angle. The instrument supports brightfield, darkfield, polarized light, differential interference contrast (DIC/Nomarski), and epi-fluorescence imaging modes, each selectable through an integrated filter wheel with neutral density, color, and iris options. A motorized X-Y stage with 100 × 100 mm travel enables raster scanning and programmable positioning. The 100 W halogen illuminator (3200 K) integrates directly into the stand, while a built-in Bertrand lens with adjustable 2x magnification facilitates phase contrast alignment and field verification. Objective availability spans standard, long working distance (LWD), and extra-long working distance (XLWD) configurations in 5x, 10x, 20x, 50x, 100x, and 150x powers.
