Purpose:
XP-212 polarized binocularmicroscopePolarized binocular is one of the most commonly used professional experimental instruments in departments such as geology, mineral resources, metallurgy, and related higher education institutions. In recent years, with the continuous advancement of science and technology, polarized binocular has been developedmicroscopeThe application scope of polarized binocular microscopes is also becoming increasingly widespread. Many industries, such as chemical fiber, semiconductor industry, and drug inspection, also widely use polarized binocular microscopes, which can be used for single polarization observation, orthogonal polarization observation, cone light observation, and microscopic photography by a wide range of users. The polarized binocular microscope is equipped with accessories such as gypsum λ plates, mica λ/4 plates, quartz wedges, and moving rulers, and is a new type of product with relatively complete functions.
