BL-ZW2
Product Details
Equipped with an adjustable and also a removable polarizer, BL-ZW2 backlight offers parallel to cross-polarization and can transmit plain light by removing the polarizer. BL-ZW2 is designed to image birefringent properties for distinguishing anisotropic from isotropic materials, detecting defects, or examining internal stresses, making it suitable for industry, petrography, and biology applications.
Removable polarizer for plain backlight illumination.
Adjustable Polarizer
Changing polarizer orientation of BL-ZW2 allows parallel and cross-polarization configurations when using a Dino-Lite polarizing microscope.
Removable Polarizer
Removing the polarizer for applications requiring plain light.
