Delphi-X Observer Polarising Trinocular Microscope DX.2053-PLPOLi

Delphi-X Observer polarising

The Delphi-X Observer polarising is the Euromex model designed for materials science, with an ergonomic design and 25 mm wide-field eyepieces. The DX.2053-PLPOLi is the trinocular version with strain-free PLPOLi plan objectives 4x, 10x, 20x and 40x, a 360° rotatable polariser, a Bertrand lens for conoscopic observation, and lambda, 1/4 lambda and quartz wedge compensators. Its iCare sensor switches the light off when the user moves away from the workstation.
