LB-590 Polarizing Trinocular Transmission and Re􀃁 ection
Microscopes with Plan Optical System
Applications
LB-590 Polarizing Trinocular Transmission and Reflection Microscopes with Plan Optical
System are specifically designed for university colleges, geology, mining, metallurgy,
pharmacy and other institutions for teaching, research and production. It can be used to
analyze and identify various minerals and specimens, it can also be used to inspect chemical
fiber, semiconductor products and medicines. Users can do single-polarized observation,
orthogonal polarization observation, conoscope observation and photography with the
microscope. Gypsum 􀁨􀁨 specimen, mica 􀁨/ 4 specimen, quartz wedge specimen and moving
stage, wrenches come with the microscope. This microscope is a set of powerful and good
quality polarizing microscope
