The Leica DM IRB inverted research microscope is the logical development of Leica’s tried and tested inverted research microscope. In this new generation of microscopes, developed in co-operation with users and laboratories all over the world, and with the experience of “150 years of optics in Wetzlar“, Leica is pleased to present the microscope system for the next millennium. Integration of all contrast methods, variable illumination and imaging beam paths together with the excellent HCS* optics, modular accessories and comprehensive range of peripherals leave nothing to be desired.
