The principle of polarizing modulation contrast is that it can converts phase gradients into intensity variations, thereby making transparent specimens clear with vivid details. The PMC system is a cost-effective upgrade for 3D appearing image. As a feature which appears to cast a shadow may not necessarily have distinct physical geometry
Equipped with high quality modulation contrast plan objective 10X, 20X, 40X, and modulation contrast condenser. There are two mode modulation contrast, turntable type and puller type
