PLM100 Series - Professional Polarizing Light Microscopy Imaging Solution
Product Introduction
The Polarizing Light Microscope is a microscope used for studying both transparent and opaque anisotropic materials. Any material with birefringence can be clearly distinguished under a polarizing microscope. While some of these materials can also be observed using staining methods, others require the use of a polarizing microscope. The reflected light polarizing microscope is an essential instrument for studying and identifying birefringent materials using the polarization properties of light.

System Advantages
Five core advantages building professional microscopy imaging platforms
Complete Ecosystem, Turnkey Delivery
Cameras, lenses, illumination, stands, and software all developed in-house. No need for multi-vendor procurement coordination, plug-and-play saves 60% integration time.
High Resolution + Large Depth of Field
45 MP ultra-clear CMOS + depth compositing algorithms provide micrometer-level depth-clear images within 30 mm field of view.
Multi-band & Low-Light Imaging
Supports white light, near-infrared, and polarization combinations with synchronized exposure of coaxial and ring lights; presents texture details even at 0.05 lux.
Flexible Expansion, Investment Protection
Standard C-Mount and GigE Vision/USB3 Vision protocols enable later upgrades to AI modules, automated stages, and multi-camera synchronization without replacing the main system.
