The Zeiss LD Achrostigmat 20x/0.30 Ph1 is a high-quality **long working distance (LD) achromatic phase contrast objective** designed for **phase contrast (Ph1), brightfield, and fluorescence microscopy**. With a **numerical aperture (NA) of 0.30**, this objective provides superior resolution, contrast, and field flatness, making it ideal for **live-cell imaging, unstained sample observation, and routine laboratory applications**. The **RMS thread size** ensures compatibility with Zeiss and other RMS-compatible microscopes.
