The Leica DM2700 P offers a level of reproducibility that is one-of-a-kind in its class, the built-in focus stop protects your samples and the front lens of the objective. For samples of equal height, the focus stop makes the focusing plane easier to reconstruct so you can concentrate entirely on your application. Color-coded lenses match the color-coded field and aperture diaphragm adjustment (CDA), to ensure that the illumination conditions are always matched to the objective. Constant color temperature by advanced LED technology.
