Euromex Objective DX.7720, 20x/0.40 PLPHi, plan, phase, infinity (Delphi-X) (53774)

The Euromex Objective DX.7720 is a 20x plan achromatic phase contrast objective designed for use with the Delphi-X Observer microscope series. This objective is well-suited for laboratory and research applications that require enhanced contrast for transparent specimens and a flat field of view. It features infinity correction, making it compatible with advanced optical systems, and is optimized for use with standard 0.17 mm cover glasses. The 12 mm working distance offers a practical balance between magnification and ease of sample access.
