Model 166-ASC

Superior in design and in performance, the 165 series incorporates a wide range of features designed for university and laboratory use. Superb optical clarity and reliable mechanical engineering assure years of top performance. Choose from three grades of objective lenses: ASC High Contrast lenses deliver excellent image contrast, Plan achromatic for superior clarity and flatness of field, and Phase Contrast lenses for viewing live specimens which require additional background contrast.
