The BD Plan Apo 7.5X is a high-quality plan apochromat objective designed for both bright field and dark field inspection. It is particularly suited for detecting surface defects such as scratches, concavity, convexity, and fine irregularities, making it ideal for precision surface analysis.
With an infinity-corrected optical design and correction across the visible wavelength range (436–656 nm), this objective delivers sharp, high-contrast imaging in both bright and dark field modes. The long 34 mm working distance provides excellent clearance, enabling inspection of larger components or uneven surfaces with ease.
Designed for use with MF-U and Hyper MF-U microscope systems, the BD Plan Apo 7.5X offers reliable performance for industrial and laboratory inspection tasks.
