For each microscope, there are a wide range of dry objectives available to match your application, e.g. 2,5x, 4x, 10x, 20x, 40x, 60x, 80x, 100x with n.A. up to 0.95 - some with extended working distance (WD). As the costs of the individual objectives vary widely according to their specifications, general price quotes are not meaningful before your exact requirements have been determined.

Through the introduction of the entry level Ergonom 1000 and 2000 series, our microscopes have now become affordable to a much larger range of customers, while providing an image quality, depth of field and color contrast not attainable in most conventional microscope systems, especially for live cell analysis for example.
