Highlights

• The LV100ND POL/DS employs optics with high extinction factors, facilitating detection and observation of high-precision optical properties.
• The LV100ND POL/DS enables analysis of birefringence, extinction angles, signs of elongation, refractive indices, birefringence magnitudes and pleochroism of asbestos.
• Changing the objectives and PH modules allows observation of asbestos dispersion colors corresponding to the refractive indices of the immersion liquid. The LV100ND POL/DS enables both quantitative analysis and dispersion staining observation of asbestos.
• A fully rotatable circular graduated stage offers trouble-free sample rotation and accurate analysis during polarization observation.
