About this product

This trinocular polarizing microscope is outfitted with high quality strain-free infinity plan objectives, extreme widefield eyepieces, and a powerful 24V/100W transmitted and reflected light halogen lamps. The polarizing microscope includes many other features, such as a EW10X/22 eyepieces (one pair standard, three single eyepieces with special reticles), quintuple nosepiece with centerable objective mounts, seven objectives (4X, 10X, 20X, 40X(S), 50X(S), 100X(S,Oil), 100X(S,Dry)), centerable bertrand lens, polarizer/analyzer, three compensators (tint plate, quarter-wave plate, and quartz wedge), centerable and rotatable stage, mechanical stage attachment, NA0.9/0.25 flip-top condenser, and a 24V/100W transmitted kohler illuminator. This microscope is a powerful instrument polarized light applications requiring transmitted or reflected polarizd light, such as mineralogical thinsections, geological samples, or toxicology samples.
